Alright, @Marek_K , here is a video illustrating 3 approaches: http://ftp.chaosgroup.com/support/V-…als_how_to.mp4
A few comments (as I’ve captured it on the go and haven’t recorded any voice):
1. You need to have a separate geometry
2. The V-Ray material I’m using is just a generic material with an image assigned to the diffuse slot
Everything depends on the geometry that is used. Therefore, I’ve put 2 examples: the picture frame in the middle has an extruded geometry, while the one on the right-hand side is just a thin wall geometry. The difference is that on the wall geometry, you can assign a model pattern and moving the model pattern will adjust the texture position (this is shown at the end of the video). While, if you assign a model pattern to a family geometry, you will not be able to move the pattern, as it actually moves the entire family.
So:
Approach 1: Adjust the texture positioning in the Revit material and then render with V-Ray (version 3.60.02)
Approach 2: Assign the V-Ray material to the family extruded geometry. Adjust the Offset U/V parameters under Texture Placement in the Standalone Material Editor until the picture fits to the frame.
Approach 3: Assign the V-Ray material to a wall geometry that has a model surface pattern assigned to it (Surface Pattern is located under the Graphics tab of Revit Material Browser). Simply adjust the material sample size width and height in the V-Ray Asset Browser to fit the geometry.
Let me know if something is still unclear.
Cheers,
Ana
