MTree - Tree creation

you can put it on the store with a link to github in the description .. like this everyone is happy.
github can be a bit intimidating for beginners.

thank you for all the work you have been doing on Mtree .. most awesome !!

 

i’m happy to do it in my free time ;-) i love the asset, so i like doing it

i thought about something else creating a private group with people wo actualy bought the asset, and upload a modified bersion of mtree

 

Quick Update to HDRP 5.16.1

Main Shaders are working.
What needs to be done:

- Brancheditor Shader functionality with HDRP.
- Billboard Shader

Anyone interested in LWRP 5.16.1?
Or other Versions of the HDRP?

 

5.7

 

HDRP 5.72 for Testing, i'll upload it on Github after i tink it's allright. If you want to test it out and leaf a Feedback, you're very wellcome to!

 

@polous you can set the cutoff to 0 then you have no leafs

 

Is the tree is editable in runtime?

 

no, you need to use the integrsted build/save option to save the tree as a mesh

 

Hi! There was a question already from somebody, but it was left unanswered, so I'm to ask again - does MTree supports GPU Instancer (https://assetstore.unity.com/packages/tools/utilities/gpu-instancer-117566)?

 

i’d say officialy no. it supports vegetation studio pro’s instancing system. but i can send you a tree made with mtree, so you can test it, let me know if you want that

 

Hi! I am making some environment assets to sell on the asset store. Can I use trees that I create with mtree in my assets?

 

yes you can, but just the baked ones , with it’s shader.

i believe the mtree wind component is ok aswell. But that’s a question for the Developer.

 

By "baked" do you mean exported to prefab within unity? I assume that any custom scripts or shaders cannot be redistributed. I mainly want to use the meshes to then re-wrap my uv's into custom atlases.

I hope to check out that bezier add-on you made once I use mtree more. Thanks!

 

Shaders you can attach, i asked this before (what can i share and what not), because the wind animation of the tree, you’ll need to have the shader of mtree to work properly

about scripts you do not have permission, have a look at my improvements. they’re all not core modifications, except faster ao but i did compile it (making a dll out of it)

 

I just purchased this nice little utility and i want to ask for some small improvements:
As leaves for me don't seem to attach completely, it would be nice if they had a corrective option for offset in relation to their branch.

And little more control over randomness via curve would also be helpful.
Also, if the 'Start' slider for branches and splits was min-max it would allow having multiple branch types on the same base in different regions.

And something i noticed: when i had randomness set to 0 on the trunk and simplify angle to more than 0 (3 - default) sometimes whole regions on the trunk went invisible (optimized away i guess)

 

hi there!

well for the leaf offset, be sure that the wind has the same parameters in the material sections!

as for the curve i did an addon for full support on custom curved tree! it’s available on github: and called Mtree Bezier Addon

https://github.com/danwipf/MTree-Addons

if transparency appears on the tree tweek on the settings(it’s kind of a bug)

 

Yes, i already found your repository earlier, all the features you have there are nice and i'm probably going to use some of them too, thank's for these contributions; but what i mean with curve is an 'AnimationCurve' exposed in the editor as for other properties.
For the leaf attachment, the 'mtree/leafs' material doesn't have a wind setting exposed; also the attachment is rigid in relation to the branch, so it's unlikely to be a vertex displacement sideeffect (also validatable by eyeballing the unity selection outline effect that doesn't respect custom displacements).
Looking at a newly generated tree the offset for the leafs this time is in 'x' direction if y means branch root->tip. I guess offsetting the image in the material may work, but it also may clip the content at the edge in UV space. But a leaf-mesh offset could mitigate that (or some other way to set the actual attachment pivot like in treeit (other tree creator) for example).
And the 'mtree/bark' shader is set up for opaque rendering, so this can't be a transparency issue (again also validatable by viewing the outline effect, or by switching on selection wire too).

 

I also just managed to break the generator

I created a prefab of the tree, deleted the scene one, instantiated the prefab via dragging (also got a pink there tree as it seems the materials weren't regenerated/created properly), added a split node after a leaf node (i know it doesn't make much sense, but it allowed it), deleted the split node again and got this (and a mesh that doesn't look properly generated):

 

i’m not the dev, but i’ll have a look in this about the wind, it happend to me aswell, and in the end i had to adjust it and it was attached as expected, use the provided wind component of mtree

 

It's really not related to the wind. It's just an offset in the UV that doesn't match with the mesh attachment. An adjustable offset will fix that.

 

Hi there, This asset looks great & I am on the verge of buying it but had a couple questions

How do the trees scale? Will they break if I scale them a substantial amount in a scene (not during play)? (x 50 for instance)

Also, is it possible to swap out the leaf textures to represent changing seasons?
Many thanks for your time!

 

@Flavelius would you like to have a uv offset inside mtree or would it work with a shader based solution?

@Lily500 for seasonal changes have a look at my repo, there’s a seasonal shader https://github.com/danwipf/MTree-Addons?files=1

for the scaling i think thats not a problem you can test it out with a tree provided in this repo:
https://github.com/danwipf/MTree-Internal?files=1
you might want to use the seasonal shader. the shaders provided are for use with gpu instancer

 

Ideally i'd like to see those requests as official improvements (also, mesh-leaf offset, not shader based) so i can use them in every project i import mtree later on (else i could just fix that myself, but that's what i'm trying to avoid as it's the reason i purchased an asset), but thanks for your help.

 

well if you scroll back a bit... the dev has temporarly abandoned this asset, and i’m just intrested in having this thing which is in my opinion really awesome alive and updated with community stuff.

i was in touch with maxime herpin for some time but then he never responded on any channel.

 

Ouch, i hope that's not actually the case and i purchased an abandonned addon :-/ (not quite cheap compared to other asset store stuff; i was expecting this in turn was worth the support..)

 

@Flavelius

Again for Leaf's wrong offset what I did to reproduce this:
- Create new Project 2018.3.5f1 and import Mtree
- Add Birch Example Tree and what a surprise it's there. (Texture: Branch_Serated)

Fix:
- Swaped texture with Palmate Texture => Offset is correct.

Conclusion:
The Bracht_Serated Texture is off and not correct! So Take the Branch Editor and create your own Branch Textures, which propably in most cases will result in correct Results!

 

The first screenshot with offset errors i posted was using a result of the branch editor unfortunately. And still in that case it would be helpful to be able to just adjust the offset instead of possibly taking a loss in quality by re-editing the texture.

 

hm default branch editor is anyway only 1024x 512 pixels => you could use my enhanced version, with real normal map support for textures from 512 x 256 up to 4096 x 2048 pixels

 

Thanks for the info! I imported the Unity package but its says the prefab cannot be imported , it may be broken. There also seems to be a missing script that should be attached to the prefab

 

This is a pretty nice asset.
One thing I am not sure about is that the leaves disappear at a distance, leaving just the branches and trunk. Which isn't particularly us full. Is there a way to get around this?

A few thing that would be nice to have is a disable button for each function. Have it so that the "Add Function" button doesn't work with the Leaf function, sense as far as I can tell none of the functions work with it properly.

Then just a couple small UI/UX thing. I would change the style of the tabs to be "toolbarbutton", to make them more readable that they are tabs, and more consistent with the rest other Unity elements.
The last small thing is that a few of the names of the variable fields are all lower case. And others only have the first letter capitalized. Where as default Unity components have the first letter of each word capitalized.

They are pretty easy to do. Took me about 30 minutes to do. But would be nice to have them as default. But I do really love this asset!

 

@Lily500 i’ll have a look into this!

@MechaWolf99 have you tried to adjust the lod levels?

 

I've updated the package => https://github.com/danwipf/MTree-Addons/tree/master/MTree Tutorials

 

@dan_wipf In the LODs the leaves should just be getting bigger and fewer. The leaves are actually fading away. Doing a bit more experimenting it seems to happen with other shaders too. But I have no idea how to stop it from doing that or what is causing it. Sort of hard to see, but here is an example of what it looks like.

 

Hi - I tried the import again - as a custom package and still have the same problem. Cannot add the prefab to the scene as prefab may be broken. Also - the missing mono script is Birch GPI. Am using 2017.4.3f1 for this
Thanks!

 

i used a blank project on 2018.3.5f2

i belive mtree does not support 2017 and below..

 

@Lily500 i reuploaded it again, as two versions. Once as Standard, the second as GPUI version. => have a look.

https://github.com/danwipf/MTree-Addons/tree/master/MTree Tutorials/Mtree Example Packages

 

have you tried with AA? maybe increase/decrease the cutoff in the shader

what do you mean with the add button does not work with leafs?

 

Ah, it looks like it had to do with the cutoff in the shader. Thank you!.

I mean that adding a growth, a split, or a branch doesn't really do anything when you add it to a leaf, right? So what is the point in being able to do it? Removing the option to do the things that don't work make for a nicer UX. That's all

 

Instead of adjusting the cutoff you can also enable 'mipmaps preserve coverage' in the texture import settings of your leaves, that should help too.

 

Any tutorials anywhere on how to make custom leaves / bark textures? It looks like they are spherically UV mapped, but I can't really tell. Blender would be preferred, but any 3d program works.

 

what do you mean by custom textures?

 

custom leaf and bark textures. I want to make like cobwebs, hanging moss, etc.. Anyways, On closer inspection it looks like the textures are UV mapped to a single quad, and those quads combined it "Diamonds" and "crosses", .

 

you might have a look at my video. i explain how to create custom leaves / objects

 

Hi, I updated to Unity 2018 4.5.f1 and the tree example is working ok. Many thanks for your support

 

Just FYI, if you're using VegetationStudio Pro with Mtree, you have to edit VSProIntegration.cs, line 32 'LODFadeCrossFade' to false.
I just had a conversation with the VSPro author about a problem related to this and this toggle should not have been enabled/used like that initially.

 

Another FYI, if you, like me experience random missing triangles, replace lines 135-136 in Splines.cs
(which is the whole AddTriangle() statement including 'if (gaps > 0)' )
with this:

Code (CSharp):

1. if (gaps > 0) // Fill eventual remaining gap
2. {
3.     for (int i = 0; i < gaps; i++)
4.     {
5.         AddTriangle(n - lastResolution + resolution + i - 1, n + resolution - 1, n - lastResolution + resolution + i);
6.     }
7. }

 

very good! thank you

 

Ever wanted realistic Ivy on your tree's like IRL? => Hedera makes it happens! https://github.com/radiatoryang/hedera

But it needs some modification on the Vertex Color Data of the Mesh, aswell on Mtree's Vertex Color (just a small change, almost not noticable but necessary!)

If anyone is intrested i'll post how it can be achieved =)

Example picture:


Vertex Color =

 

Very nice! That looks super realistic.

 

yes it’d be super cool to have such trees!

hopefully the developer fixes the leaves position
