MAHONiMATION Posted September 9, 2015 Share Posted September 9, 2015 Hi there, I seem to have a massive issue at the moment regarding a piece of geometry made in Maya and imported into Houdini. Basically it looks as if the normals of the model have gone a little broken. Everything looks fine in Maya when exporting and the rest of the model looks great too. Anyone encountered the problem as well? Thanks! Quote Link to comment Share on other sites More sharing options...
michael Posted September 9, 2015 Share Posted September 9, 2015 how was it exported to Houdini? can you attach a simple example for us to have a look at? Quote Link to comment Share on other sites More sharing options...
MAHONiMATION Posted September 10, 2015 Author Share Posted September 10, 2015 It was simply exported to Houdini from Maya by selecting the geo in Maya and going to File > Export Selected and then exported as an OBJ. Sure! I'll attach a simple example to this Simple example download location: https://www.dropbox.com/s/gymwq8w5jjvtt9a/GEO_TEST.zip?dl=0 Quote Link to comment Share on other sites More sharing options...
michael Posted September 10, 2015 Share Posted September 10, 2015 can you submit this to support (geo files yes, but no need for the rat file): http://www.sidefx.com/index.php?option=com_content&task=view&id=768&Itemid=239 it's for sure a winding issue but it's beyond my shading limited brain... I made a very simple material (uvcoords>surfaceColour>surfaceModel>surfaceOutput) and it rendered just fine...so there is something that our shaders are doing (or not doing) that can't deal with the winding of that geometry.
