Material editor - decal size node

[nitrooo]

Please add "Decal Size" node. Now there is only "Decal Radius" node but decals have also width and height. I think general "Object bounds" node would be very useful too.

Could you please let us know the specific use case you’d like to achieve with these parameters in the shader? We’d appreciate a bit more detail.

Thank you!

I want to tile decal texture according to its world size. I have achieved this by extracting width and height from Decal Matrix Projection node but this is awkward and heavy. I think instead of Decal Radius it could be Decal Size where x=width, y=height, z=radius.

Looks like that specific task can be solved also via Object-space mapping:

No need to know texture size or get this info directly from projection matrix.

Thanks!

Yes it can. But what if I want to know, for example, if frag position is at half width of the decal? I still think that Decal Size and Object Bounds nodes should be available. My first thought, while playing around with decal material, was: where is width and height in addition to radius?
