I would like to project a texture using projection mapping.
Is there a way to do texture mapping without UV unwrapping?

Yes, but only in one axis. planar mapping.

Use a ‘sampler Info’ node input to a ‘multiplyDivide’, and output X,Y or Z into Uv Coord of the texture.

pointObj mappes the texture to the object
pointWorld fixes the texture to the world
pointCamera projects the texture from the camera

In Blender you can do it this way

Puzzles and JS coding. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

Yes, kdv. But unfornutatedly Maya doesn’t have anything equivalent of the object output in texture coordinates in blender.

In the first post I didn’t notice mentioning “Maya” )))

True! But it is posted in ‘Graphics / Maya’ section of the forum. ;)

Maya do have a triplanar mapping, but not supported by verge3D

Ahhh… Now I see. My bad
