The dirt map breaks when it's used in a triplanar map.

It works as expected until the last slot (negative z) is used. It's not consistent though. I used instanced maps in my test, but if you use copies of maps, you get different though still broken results. Tried in a couple different versions. v 4.02.1 - 6.14 was used for the screenshots.

Hi senorpablo,
I cannot follow your reasoning there, could you share a scene or a nodegraph screenshot please?

Here's a file. I uploaded one in the original post, but it just disappears without warning when I hit upload(I guess it's too large?).

The teapot on the left has a glossy material with a mix map in diffuse. The mix map is comprised of a dirt map controlling the mix of red and blue colors. Dirt map works as expected.

The teapots on the right use the same map, but it's used in a triplanar map. When all the slots of the triplanar are used, the dirt map breaks. When it's used in all slots but the last one, it works as expected(though you have one empty material slot).

I know for certain this worked correctly in the past as I've used it in a material which I'm revisiting now which lead me to discover this issue.

Hi senorpablo,
thanks, this issue is in SA too, so it does not depend on 3dSMax plugin.
I will report it to developers.
