I’m trying to make a hologram material but would love to know if its possible inside UE5 to randomly select a few verts and then have them use a different material or use a different attribute.
If not I could just separate a few verts in blender and give them a different material but would prefer to have be dynamic.
Any comments would be great, thank you.
This is job for niagara particle systems.
I am not sure if you can get vertices from skeletal mesh right to niagara.
But it should be possible to write blueprints (Slow) or C++ function that reads those points and exports to something niagara can handle.
Niagra does have a vertex sample type for vertices.
Make a new system and add a Skeletal Mesh Location thingy to the particle update section. Under sampling for that, pick Surface (vertices), random, and spawn only for the random evaluation, and it should follow the animations:
For the base mesh material itself, tick wireframe in the advanced dropdown of the material
result node, and plug a color multiplied by a >1 value into emissive.
That said, using verts looks kinda busy if there’s lots of polygons.
If you’re going for an effect similar to the celestials in Warcraft, it might be better to use bones mode on the skele mesh sampler. Pretty sure that’s how they did Algalon and the celestial dragons in WoW.
lovely, thank you very much. Will try this when home from work.
Thanks for the help.
