“Are you referring to the blue bead to the right of the word Displacement?” I can’t move the blue bead to Texture A, for example.
“Or the object to the left of the word that looks like a press down button?” The slider on the left side will not move.
“Just to the left of the word is a small window displaying numbers. Are you able to left click on that window and highlight it?” Yes, and I can enter a numeric value but it resets to 0.
Sounds like another one of those mystery errors that seems to hit one or two people but nobody else. I got one, not the same but essentially I can’t import .obj’s directly into Bryce although others can. I can import other formats but when I try .objs Bryce says “Unexpected error (failed creation)”. I can import .objs though if I import it into Studio and then send it to Bryce over the bridge. Anyway when I ask, people have never heard of the error and tell me they can import .objs into Bryce directly with no problem.
Now as far as displacement I’ve never tried that. I have however seen quite a few people way more experienced with Bryce report that it’s flaky and is prone to causing Bryce to crash. As a note I paused here, open a blank scene, created a single Bryce rock, went into materials, put a blob in channel A for displacement let it apply the default DTE setting that popped up which was waves2 I think? I was able to go to attributes and manually adjust that setting David showed but it seems to have a maximum of .1 because I could set .01 on up to .09 and it would hold but anything above .1 would revert back to .1 as soon as you close attributes. It would distort the rock in strange ways similar to what guss posted if I adjusted the slider next to displacement. I didn’t do more then the one rock and playing with it’s setting and rendering but I got no crashes.
