Deal ...

Edit :
Can you post a picture with the 'Dirt Texture Option' activate?

 

Mask With Alpha - Is a dirt texture strength measured by texture alpha.

Oh sorry, my bad : i mean a result picture (statue, teapot) with a Dirt Texture activated.
Nevermind. I've faith in your product.

 

Shadow strength defines dirt texture visibility.

Hi,
You're mentioning this is also included with Mesh Materializer.
But I can not find "Occlusion Render" option in Mesh Materializer.
Is this feature only available on this asset or an update is coming to MM with "Occlusion Render" feature?

 

Occlusion Render solver will be added to Mesh Materializer in coming update.
Raycast solver is already there.

Edit:
Ambient occlusion and indirect lighting generator will be the same as in Mesh Materializer.
All features added to this plugin will be added to Mesh Materializer too.

Hello, I just picked up your vertex AO baker, and have a problem. Say I have a bunch of copies of an object in the scene, like this:
http://imgur.com/lDoA7n4

And I bake AO on it - instead of every instance getting its own values, they all share the values of the first one:
http://imgur.com/C4ms44T


Which is obviously broken.

I notice that if I combine them into a single mesh, then they work:

But I need them to be separate. Is this a bug? Is there a workaround?

Thanks,
Ocean

 

It is not broken
In your case you need to change Mesh Asset Name property to some with (ID).
For example: (meshName)_(ID).

By default it's set to (AO)_(meshName) - it means that generated meshes (not main prefab asset) will have original mesh name with AO prefix.
If in target selection are multiple meshes with same name - each one will overwrite previous inside save folder.
Property with (ID) prefix/suffix will prevent it. As every object in Unity has unique ID, converted meshes will have also unique names and will not overwrite each other inside save folder.

That works great! Thank you, it's an excellent tool!

 

Looks good, +1 for runtime support for procedural stuff. What will the new price be if I may ask?

 

Price will be changed on 1st of November with 25$.



Amazing Assets - YouTube Facebook Twitter

 

Deal at $15. Thanks. But $25 still a good price.

 

Update v1.1 released.
• For Occlusion Render solver Include Environment parameter is replaced with Layer Mask parameter.
Layer mask defines scene objects that interact with Ambient Occlusion generator.

Hi Arkhivrag, I noticed you use a custom shader.
What do I have to do to still use the asset but have a different shader?

 

Custom shader is used only by Render Occlusion solver and if you change it final AO result of course is not predictable.



Amazing Assets - YouTube Facebook Twitter

 

I don't really understand.
What I meant to say was, can I have the standard unity shader(PBR), that uses the GI etc AND add the AO data to it, somehow? I tried using 2 materials, with PBR underneath, but the AO shader doesn't have any transparency.
Is this even possible?

 

OK, now I understand your question.
All generated data is save inside mesh vertex color and to use it you need shader with vertex color support.
Package contains only one such shader.

To use mesh vertex color with other shaders and effects you have to manually modify them, or ask shader author (if purchased on Asset Store) to add mesh vertex color.

And what about saving the 'AO result' as a texture?

 

It needs uv layout per-pixel AO calculation, that is not purpose of this asset.

Update v1.11
• VacuumShaders assets synchronization. Required update for all VacuumShaders assets.
• Added Vertex Color shaders: Unlit, One Directional Light, Legacy and Standard shaders.

Hi Davit. I have mesh Materializer and trying to just add AO to my mesh.

But whenever I try, its always creates a faceted version in white. If I try to put the material into Default Material slot in your asset window, it then keeps the original mesh structure, but doesn't apply any AO? How do I get it to keep the original mesh and texture resolution but add AO to it.

Using your demo scenes

 

So you are having problems with Mesh Materializer and not with this asset.
Then why not use Mesh Materializer forum: http://forum.unity3d.com/threads/mesh-materializer.293796/
Anyway, faceted version will not be created unless that option is selected.
As for AO baking make sure you are using VertexColor/Unlit shaders, that shaders display only vertex color and help you find whether generated results are satisfied or not.
Included Vertex Color shaders support texture and mesh vertex color using simultaneously.

P.S.
Not David, but Davit.

Because its related to the AO which is the functionality i am having an issue with. Seeing as this is part of MM, does it really make a difference?

Ok so made all those changes but still not the result im looking for. It needs to be the original mesh and texture but with AO baked on top of that. The one on the bottom right is the new created mesh, it firstly has a nulled down texture and not the original and also didnt receive the AO. I made it red so it would stand out, but nothing there.

Thanks

 

OK, continuing discussing Mesh Materializer in Per-Vertex Ambient Occlusion forum.
Can you generate only Ambient Occlusion to see if it works?

Here is what I got

hey man no need for your sarcasm, becoming very tedious very quickly.
Secondly thats not what ive explained twice now. The second one doesnt retain the original material, i dont want flat shaded stuff. I want my original mesh and material but with AO baked in.

 

1. It is not sarcasm, just fact forum messed up.

2. Images I show you display data baked to vertex color, meshes there are not flat, but copy of original.

3. As I wrote above included Vertex Color shaders support texture and mesh vertex color simultaneously.
So when you bake AO for your mesh use any of included Vertex Color shaders. If using Unlit or One Directional Light shader check Texture using flag inside material editor.


If you are using some third party or custom shader, then it must have mesh vertex color support.

Thats it, but im stil not sure how you got there. I followed all instructions and have the default shader set to vertex/unit as per screenshot. Maybe a quick video or step by step screenshots.

You cover all other functions on your youtube channel but nothing that gets to this stage, which is a very important part of using this asset. Thanks

 

Yes, asset has improved so much comparing with the first release that tutorial videos are slightly oldish.

Have you considered adding DICE style transmission generation too? (Invert normals, bake AO, restore normals)

 

Can not find much info about 'DICE style transmission' but here is quick results of - Invert normals, bake AO, restore normals

Left one is ambient occlusion, right one what you asked for.





Amazing Assets - YouTube Facebook Twitter

 

Hmm no that doesnt look right, here is a link however https://www.google.co.uk/url?sa=t&s...ap-and-convincing-subsurface-scattering-look/

Its a neat way to get translucency and having it baked into vertex colors could be handy

 

So how did you make the blend with the original texture and AO?

 

Thanks, will check.

Ambient Occlusion is just saved inside mesh vertex color and then inside shader it is multiplied with sampled texture.




Amazing Assets - YouTube Facebook Twitter

 

Please show me using screenshots, i really dont know what you are refering to. thanks

 

After baking AO use any of provided VacuumShaders/Vertex Color shaders.
If using Unlit or One Directional Light shaders enable texture flag inside material editor.

I've got a bunch of data packed into vertex Alpha that I want to preserve, while still baking AO into RGB. Is there any way to bake RGB without also stomping on whatever's in the Alpha channel?

Thanks

 

Update v1.12
• Fixed, losing some of sub-meshes when 'One Sub-Material' option is selected.
• Fixed, losing some of sub-meshes when 'Combine Into One Mesh' is selected. Final combined mesh will have only one sub-mesh (itself).
• Fixed original mesh vertex color blending with generated colors.
• Inside editor generated data can only be save inside vertex RGB or Alpha channels.
• Run-time script generator function changed. Removed 'SAVE_CHANNEL' enum option.
• Added example scene for run-time blending mesh vertex and generated colors.



Amazing Assets - YouTube Facebook Twitter

 

Yes,
Inside editor generated results can be combined with original mesh vertex color.

If blending inside RGB channel:
finalColor.rgb = vertexColor.rgb * generatedColor.rgb
finalColor.a = vertexColor.a

If blending inside Alpha channel:
finalColor.rgb = vertexColor.rgb
finalColor.a = Grayscale(generatedColor)

Inside run-time scripts it is up to you how mesh vertex color is blend with generated data.

@Arkhivrag I'm trying to understand your plugin, is it at run-time or pre-computed (baked)?

Also, could you tell me if it would meet my specific needs as mentioned below.

I have a 3D FBX model of an airport that is split into 3 separate meshes inside Unity: the ceiling, the airport with all the details, and the outer wall. Due to the requirements of the project I'm working on the scene needs to be all white with Ambient Occlusion everywhere.

I'm trying to weigh the cost of using a plugin tool vs having my artist bake the ambient occlusion and lighting into the textures of the models.

I was wondering what are the benefits of using this tool vs having my artist do it? My artist mentioned that if they were going to bake the AO into the textures of the model, they would have to unwrap UVs on every part of the model first. Does your plugin automatically handle unwrapping UVs, or does it handle AO some other way?

Thank you.

 

Ambient Occlusion and/or Indirect Lighting is generated per-vertex and saved inside vertex color, no UV unwrapping is required and no UV unwrapping is done.
Plugin works both in editor (generates mesh asset with baked AO into vertex color) and in builds using run-time API.
Note, generated AO quality depends on mesh vertex count, if models are very lowpoly then better provide custom textured AO.

Thanks for the info. Do you know if your tool has a demo version?
