Hey Jordan!
Unfortunately I don’t have any VR kit and (still) didn’t test these effects on my own. However, some of my customers reported that two effects not working well in VR. These are Edge Detect and Emboss effects. Since both of them are using the Convolution Matrix algorithm, probably more (3 or 4) to add to not working list here.
I really don’t need a VR kit for my own for any other use than testing these effects. But also couldn’t find a way to emulate VR in PC without a kit to test.
If any other VR users here, please share your results with this fellow dev!
