I'm currently trying to use vray proxy for cache'd out animation on a hair sim. Loading the cache onto a vray proxy so that lighters only have to interact with one object that has no modifier stack. The issue I'm running into is the hair uses a vray hair material with an hdri map slotted into the transmission texture. The vray proxy hair is not respecting the transmission texture. Essentially it comes down to the look of the hair is not the same between the hair not using the vray proxy and the one using it. Same material and the difference I've been able to figure out is the use of a texture in the transmission slot. |
| To ensure that the hair UVs are imported correctly into V-Ray proxy object please find the option Force first map channel in Proxy params, Compatibility section and turn it on. Marsel Khadiyev (Software Developer, EPHERE Inc.) |
| I have tried that. I forced the channel on 0 and 1. It is a UDIM setup for textures. Using the HDRI method of reading UDIM's. I also tried using max's multi tile texture, to less success. Even loading any texture, just a regular bitmap(.tiff) file into the texture slot changes the results from the normal hair and the one in the vray proxy. Without a texture in the transmission slot, it seems to render the same. |
| Ok, I guess we'll need to try and reproduce this problem Marsel Khadiyev (Software Developer, EPHERE Inc.) |
| ok, its long hair, it's a vray hair material with a brown shiny preset and a hdri udim with 2 textures plugged into transmission texture. If you guys are able to reproduce please keep me updated, thank you for looking into this. |
