  • Performance and resetting issues with VrayOSLTex

    I've got two major problems with VrayOSL tex:
    1) I'm trying to redo my max osl stuff with vrayosl and when I try to convert it, the vray version just tanks in performance. The max one handles multiple outputs internally, but the vray one needs VrayOSLOutputSelector nodes, which seem to reevaluate the tree each time, which then completely tanks the performance. I could be wrong on this but it sounds plausible. Fact is, the performance is really bad in comparison. Orders of magnitude slower.
    2) The VrayOutputSelector nodes lose their settings on max or scene reload. My guess is that the quick shader in the VrayOslTex is recompiling and the Outputselector nodes then lose their setting. (edit: they also reset when an .osl shader is loaded from disk)

    I can't upload the scene file here directly so please let me know where to send the file privately with additional explanations (it's a bit complicated).

            Hi we reviewed your scene carefully.

            The slow down issue is reported in our bug tracking system for developer review under VSLANG-169

            For now you could load an osl file as a workaround to the resetting issue. If you copy your shader in a text file and save it as .osl, disable the quick shader checkbox and load the .osl file there will be no more resetting.

            Also the values in parameters tab will be dialled back to default. You will have to re-enter them manually.

              Odd, I was sure I had tried that and thought it had reset as well. But I tried it again now and it seems to work, my bad. Still, with the slow down it's unfortunately not going to help us at the moment. I have to wait for at least this performance issue to be resolved.

                Hi, the VRayOSLOutputSelector resetting issue is fixed. If you'd like, download the latest version and test it.
