Materials to Unreal May 13, 2021, 4:30 a.m.

I've been trying to find the best way to get loads of models with different materials with multiple Udims to Unreal without the need to manually set everything in Unreal.
USD was my first idea, but I could not yet get it to work, so I thought: let's just do this via Engine.
For this I used the principled shader and did a test with only 1 udim manually set to 1001, and that works. Yeah!
Now if I use %(UDIM)d it breaks.
I do not want to have to set a seperate material for every udim.

Is it possible to use Udims to transfer materials and textures to Unreal and what would be the best way?

How to detect flipped UV islands? Jan. 8, 2020, 10:17 a.m.

If the uv-islands are from a connected piece of geo, you can use the polydoctor to wind uv's to the majority of the connected geo.

How to I extrude points to make edges ? Jan. 8, 2020, 10:12 a.m.

Here's an example for that.
Scattered some points, added a randomized Normal, gave it a number-attribute, displaced the points along a normal with a adjustable amount, the merged them back with the original points, and with an add sop, using “number” as group by attribute, tada.
Hope this helps.
Cheers,
