Fostertron Posted November 10, 2015 Share Posted November 10, 2015 (edited) Hi Guys, I'm nearing the end of the tunnel for my project and I'm getting to some of the little details! Thanks again for the help so far. I've modelled a yacht in Rhino and I've been using Vray for the rendering so far. I'm now using Mantra for the animation side and I'm struggling to achieve the same effect as in Rhino. I basically want to stretch a single wooden plank image onto individual surfaces which represent planks. Here's an example: You can see that the planks need to be individual since the boards wrap into the centre etc. I can either convert into polys (triangles) in Rhino and import or import Nurbs go from there. When I've tried to import an OBJ from Rhino, I can't seem to wrap the texture, it simply projects it without 'curving' it as it does within Vray for Rhino. Is it because it's triangles? I've tried using Edge loop and UV Pelt but I'm not sure about the workflow. Here's an image of the decking and a wood texture. Here's a sample of the decking OBJ: https://www.dropbox.com/s/32kk718z65pogrp/Decking%20Sample.obj?dl=0 Thanks again for any help!

3__ Posted November 11, 2015 Share Posted November 11, 2015 (edited) see attached, the UVs are aligned to each plank. curving UVs for bent sections (rather than cut) is a bit trickier... uvs_from_planks.hipnc Edited November 11, 2015 by cpb Quote Link to comment Share on other sites More sharing options...
Fostertron Posted November 11, 2015 Author Share Posted November 11, 2015 Thanks very much Craig! Thanks for your time. I'll have a good look at these nodes and create the scene from scratch using yours as reference. I notice that the texture on one of the planks is stretched compared to the others: I assume it's a problem with my model data but what do you think might be controlling this?

3__ Posted November 12, 2015 Share Posted November 12, 2015 (edited) couldn't reproduce the problem... see attached for another file using the wood texture, plus a (nasty) attempt at curved UVs. curved_uvs_from_planks.hipnc Edited November 12, 2015 by cpb 1 Quote Link to comment Share on other sites More sharing options...
Fostertron Posted November 14, 2015 Author Share Posted November 14, 2015 Hi Craig, Sorry for the late reply and thanks again for your time. That seems to have done the trick for some reason, I'm not sure why but your 'nasty' attempt looks really good to me! It's perfect for what I need especially considering the scale and distance at which I'll be rendering. Thanks again, Kyle Quote Link to comment Share on other sites More sharing options...
