nemsi Posted January 4, 2019 Share Posted January 4, 2019 (edited) Hi guys, i would like to know if it's possible to add 2 or 3 differents uvs (..maybe more) on an object and name it uv1 uv2 uv3.. And then call it in my shader like uv1 for noise texture, uv2 for wood texture, uv3 for logo... Sorry if it's a silly question Edited January 10, 2019 by nemsi Quote Link to comment Share on other sites More sharing options...
Skybar Posted January 4, 2019 Share Posted January 4, 2019 (edited) Yeah why not, try it. edit: I mean if you want different materials like that you probably have to do it another way.. But just different textures with different uvs it should be fine. Maybe need some way to mask between them though if they're overlapping. Sorry maybe I was too fast to answer Edited January 4, 2019 by Skybar Quote Link to comment Share on other sites More sharing options...
Mark01 Posted January 4, 2019 Share Posted January 4, 2019 Yes, as David said, it can be done but I don't see the need for multiple UV's. I think you mean 1 set of UV's and then multiple textures? Quote Link to comment Share on other sites More sharing options...
nemsi Posted January 4, 2019 Author Share Posted January 4, 2019 Hi, for exemple in Softimage you can attrib multi texture projection to an object and for each texture map you can set the uv you need. Sometimes you need a projection for a logo and an other for your texture (exemple for bump..) It's helpfull and fast when you don't have time to unwrap and work on uvs.. Thank you guys Quote Link to comment Share on other sites More sharing options...
anim Posted January 4, 2019 Share Posted January 4, 2019 works the same in houdini in nodes like UV Project or UV Texture you can specify the name of the uv attribute, it can be any valid name then in shader use UV Coords node and put the name there, it will pull "uv" attribute of that name Quote Link to comment Share on other sites More sharing options...

nemsi Posted January 9, 2019 Author Share Posted January 9, 2019 Hi Anim, thank you for your time, I'm doing this but doesn't seem to work.. Here a simple scene, Perhaps i'm doing something wrong or Redshift doen't understand uvs attribute.. Ps : Thank you MilesS1, I saw this tutorial, but it's more like what Anim said, what i need. Thank you for your time. uvTest.hip Quote Link to comment Share on other sites More sharing options...
davpe Posted January 9, 2019 Share Posted January 9, 2019 i don't know what you expect to get but your example works. you've got two uv attributes and redshift renders two ramps oriented by those uv attributes. isn't that what you want?

nemsi Posted January 10, 2019 Author Share Posted January 10, 2019 I get some weird effect about reshreshing.. sometime it takes the texture and sometimes no... i will inform Redshift forum about this.. Thank you. uvIssue.hip Quote Link to comment Share on other sites More sharing options...
