Feedback World space trail textures

Thanks for making this available!
I will test it out and let you know.

 

Perhaps an idea for optionally making the trail project to a ground surface like decals do?
This way we can use it for car tracks on the road surface.

 

1. Line Renderer is missing World Space Texture Scale option
2. If Texture Scale has been implemented for the World Space texture mode I strongly believe texture tiling should be implemented for all the other modes as well so that we can adjust tiling without having to make a new material copy and modify texture tiling there
3. Texture Mode is called World Space and yet when I am scaling Line Renderer up/down texture tiling behaves as if it was generated in the local space of Line Renderer. I definitely think this is a good default behaviour but I also would like to see a param which defines how texture tiling behaves when object is scaled, similarly to Scaling Behaviour in the particle system. Should scaling affect positions of points only and keep the world space tiling or should it affect position of points but also keep the relative local space texture tiling, it could be an useful option to have. But it's a very low priority, at least for me.
4. It's probably due to it being an early build but line renderer with Loop enabled stretches the texture in some segments

All in all I think this works quite well. True test will come once it's implemented for the Particle System but I am quite happy with how this early build works. Thanks!

 

Just "Static" or "Local Space Static"? I think just "static" sounds as if it was not possible to animate it with a shader or something in that ballpark. World Space Static / Local Space Static might be a bit better?

 

What about "pinned" or "fixed" ?
or maybe "solid"

 

Oh God, you don't even know how excited and grateful I am for adding Texture Scale to the particle system. THANK YOU! It's such a massive workflow improvement!

Would it be too much of a stretch to have separate U and V texture scale parameters?

As for the Static texture functionality it works exactly as I imagined. I tested how it behaves with scale applied in the Transform and it also does behave as I'd expect. Great job!

 

Yes U/V separate will give more control, I would welcome this too

 

I would say for my use case center is most of the time center of the line.

For example here are some car tracks, I would cut one off them into a square and tile them on the line.

Ideally I would like to have a seperate alpha texture so I can create some variety and break up the texture a bit, but I can also do it in a single texture if I make a long texture that is tilable.

 

Centre point makes the most sense for me as well although you know, having actual scale aaand transform (scale and offset) controls can never hurt! But I don't know anything about cost implications so if this is too much then centre point would be the most reasonable thing to do I believe.

 

Thanks for updating these tools!
Its been a welcome addition and yes you can ship it and iterate more after shipping.

I know it takes a while to land in a release build so I think it good to have it in there in 22.1 before the new features are locked.

 

@richardkettlewell Thank you so much! Is this feature in the most recent versions of 2021.2 that we can download via the hub?
Thanks!

 

@richardkettlewell While this is working great on the Trail Renderer system, I've tried working with the static trails on particle system trails without any luck. In both 2022.1.0a13 and the specifically mentioned 2021.2.0a20, I seem to get the same behavior as DistributePerSegment. The Texture Scale field also doesn't seem to affect the scaling, no matter what texture Mode it is set to use.

I've attached a gif to illustrate the difference I'm seeing. Perhaps I am setting something up incorrectly?

Edit: I've figured out that this is a limitation of the ribbon type particle trail. This seems to function as expected with the particle type trail. If this is the expected/intended behavior you might consider hiding the static option, along with texture scale field when it's set to the ribbon type?

 

Thanks so much ! is exactly what i was looking for. I just have a question. I would like to fade out the last part of the trail renderer. When the trail starts to dissapear for example in a wheel trail, looks like too abrupt and i was thinking how i can achieve a fadeOut of the part of the trail that is going to dissapear. Can i achieve this effect in some way ? .
Thanks in advance and really appreciate your work listening the community.

 

Thanks Richard, i putted the material in particles and now works like a charm. Now this tool become super useful thanks again !
