Hey guys, I'm working on some procedural tools and I need to add points on 2 primitives (they are approximately the same) to then add polylines for each pair of points (to make some grooves like there is on haussmannian building rooftops). This screenshot may help to understand : The thing I do for now is resample the bottom prim, and then use primuv() to sample the pos based on the @curveu (or u in the screenshot) attribute on the upper prim, and for the line I have a Add node -> by group -> by attribute, and it works like a charm; until the 2 primitives have different parametric coordinates. Sometimes it have offset, or even it's inverted, and the points aren't interpolated as I want. So, I wonder if there is a way to copy the uv coordinates from one primitive to another one, or a better solution to this ! Cheers,

Hey fawkes! Any Ideas on hot to achieve something like this? Been thinking about using some emission group with a POP and some trails. My doubt is how to mesh the stuff and give it the subtle cloth dynamics. Maybe a Geometry or Point Vop with a noise. How about UVs here? Any Ideas? Cheers!

Hey guys, I really need some help here, I'm in the middle of a project and can't export the simulated cloth with proper UVs (exporting it as alembic / must work in Maya) Here are some statements about the situation: - if I export the grid mesh, with no simulation, the UVs are read correctly outside of Houdini; - if I export the simulation, directly from the dopimport1 node, it doesn't work outside of Houdini; - the UVs are ok when I import it back to Houdini (and unpack the geometry); - the cloth is gettin' ripped on my original scene, this way I can't use an attribute copy to get the uvs from the original mesh (since it's point count is changing); - If I import it to 3ds Max, it work's at the first frame but as soon as I run the timeline it get id of the uv. I can get the 1st frame uv to stick to the object if I add an Unwrap UVW modifier to it. Tried to export it from Max to Maya but it doesn't work; I did a quick test here in a much simplier scene, with a plane only and get the same problem. The scene file is attached + 2 exported alembics (with and without simulation) Thank's in advance Cloth Problem.rar

Hello guys, i think this is a peculiar problem I have to "fuse" 2 meshes and VDB looks just perfect for the job. The 1st mesh is an orange (alembic) and it have some perfect UVs. What I did is a simple vdb setup to combine the 2 meshes + an attribute transfer to get the uvs from the orange but, unfortunatelly, it looks like some of the polygons are still connected in some parts where it shouldn't be. Does anyone knows a solution for this? I can't share the original scene so I've recreated it in a simple way. The original one have a face to mix with the orange. here's the images + scene file (with abc) in case someone can have a look at it Thx again, Alvaro UVs Transfer Problem.rar
