Hello,

I`m trying to get sand displacement on my geometry but it seems like atribute from map only works on 1001.
And I`m working with a trimuvs. trimtexture whatever you want to call it,
Ix there is the option UDIM filename extention but i generally dont want to make 100 files.

EDIT: this is fixed by placing a modulo in the block inside the afmap.

Hello i have made a simple instancer.
The problem is that it only works if pack geometry before instanceing is ticked and the target andanother input are always World inputs.

Is there a way to set these by default ?

It`s not that hard there is a library that someone uploaded on the forum that has a wrapper that makes this a 1 node solution.

Here`s the pack. some of it is a bit outdated needing you to go in and flip some switches so it`s not ideal but it shows what you need.

also i think in just karma there is a 1 node solution to this.

Does annyone know if there is a way to setup stamppoint so that it auto combines normals?

Bonus question annyone know if you can apply a different noise per instance becore it go`s into the stamppoints ?

Hello so i notised that my hextile size was of a weirdly low quality.
i assumed this was becouse the hextile is not useing the same 4k textures that it gets trough input.

I then tried piping in a sizeref. but even just importing a 1k sizeref is taking over 10- minutes to process (on windows).
so i`m confused about this hebaviour.





(there is also a resolution problem with the ramp nodes but that's not related to this issue.

Hello so I was texturing an axe and wanted to get reflective metal but it seems that the default environment just reflects black. I then tried adding an HDRi as per standard but that seems to be even worse as it also reflects black but without highlights.

am i doing something wrong ? i feel that this should somehow work.

Hello that workflow doesn`t work verry well.
If you use vellum post process you can get things to work better.
It might require some attributes like thiquesness or something if you can`t immediatly get it to work run a normal clos sim and pipe that into it and c what the used attributes are called.
