Hi there,

i am working on digital environments and want to use decals on them. I figured the “GameDev Decal Projector” is what i need, but honestly cant figure out how to use it or what it is actually doing? Can somebody explain? What is meant by “Projection Mesh”, the mesh i want to project onto my environment for example? What is the heightmap for? Could not find a tutorial for it.

Just to explain, what i want to do is add detail to my environments in certein places on top of the ground texture. I know i can do it by using camera projection for uv, but i guess there is a better way.

thanks

Hey,

Its correct we don't have a tutorial for that tool yet. I'll put it on our to-do list!
In the meanwhile, perhaps this could be useful: https://vimeo.com/263406952 [vimeo.com]
See timestamp 14:20. Luiz is showing how it works.

Please make tutorial for this or at least update the help, now it is unusable as we have no clue how to use it. The video is for some early version and this does not work that way. The help is for some early version.
All I get is the area where the decal is supposed to go but when I add a height map (bump), nothing shows. The inverted height map as AO makes the bump visible but does nothing else. The Place is totally ununderstandable, I have tried to connect geometry to third input but it will not show and I have no idea what to do with decal list and where to get the decal index.
And what is Decal target points?
I have UV, normals (Normal node) and quick material but still nothing.

HEEEEEEEELP needed!
