Devin Johnston Posted March 23, 2017 Share Posted March 23, 2017 I just switched over from 3.2 to 3.5, I've set up 2d displacement a million times with no issues until now. When I apply it to an object all it seems to do is generate noise, anyone else had this problem? Link to comment Share on other sites More sharing options...
Devin Johnston Posted March 23, 2017 Author Share Posted March 23, 2017 Ok it's not displacement that's not working, there's something strange going on with UVW mapping. I'm wondering now if the update I did to Max to SP4 broke something or maybe it's a bug in Vray? When I scale the material properly it's way to big in the view port but renders correctly, I've never seen this before. Link to comment Share on other sites More sharing options...
Nicolai Bongard Posted March 24, 2017 Share Posted March 24, 2017 This may be relevant: The 2D mapping (landscape) method will ignore the Tiling parameters specified in the textures themselves; as a side effect this means that it will not work with the Real-world map size options in the Bitmap and other textures. Instead, you must modify the UVW coordinates of the object, or use the 3D mapping method. The 2D mapping (landscape) method only supports one UV mapping channel.

John Dollus Posted March 24, 2017 Share Posted March 24, 2017 (edited) In the manual under 'notes': https://docs.chaosgroup.com/display/VRAY3MAX/Displacement+Modifier+%7C+VRayDisplacementMod#DisplacementModifier|VRayDisplacementMod-Parameters 2d method is a bit obsolete with the improvements made to the 3d displacement method over time.

If I'm reading this correctly it's saying you cant adjust the bitmap within the texture you must use UVW mapping. That's exactly what I'm doing but the results I'm getting are compleatley messed up. The displacement map is on a wall from what I understand about 2D and 3D mapping 2D is the better option here, however I've tried 3D and it makes no difference it just looks a bit softer.

Nicolai Bongard Posted March 26, 2017 Share Posted March 26, 2017 The way i understand it is that in your bitmap settings you disable real world coordinates and set your tiling to 1, then you apply a UVW map modifier to your object and scale it (not adjust tiling, just the size of the in this case probably box mapping) and it should work ok. The text i previously posted was from here: https://docs.chaosgroup.com/display/VRAY3MAX/Displacement+Modifier+%7C+VRayDisplacementMod#DisplacementModifier|VRayDisplacementMod-Notes Link to comment Share on other sites More sharing options...
