first off - awesome there is already a cr3 daily build !!
→ question - is it in the actual state of the product possible to have displacement with texture mapping a and on top a meterial with texture mapping b on the same object!?
i know c4d has its was of doing things but at the very moment i cant figure it out…
in the cr2 beta 2 it was possible to “stack” 3 material tags on a object - from left to right - displacement with mapping a , a normal material with mapping b, and an totally opaque material wich mapping a again…
so the displacement is taken from the leftmost tag, the material on top give the look and the displacment from first material takes texture mapping from third materiall..
i know its a weired little hack but in the acutal beta 3 it does not work any more
instead, what does work is the projection shader but this one is a beast to setup as there is no visual feedback for the mapping, at least not out of the box …
Anybody else notice that with this daily the material preview update is taking ages when Displacement is in play, compared to Beta 2? Got a material here that went from 1 to 2 seconds to up to 8 seconds when I switch on Displacement.
I compared Beta 2 and the latest daily in a scene. Don’t mind the crappy sugar material.
In R19 (with beta 2 of corona installed), I got a rendertime of 1:18 for 6 passes (don’t mind my crappy PC either), in R20 with the latest daily of Corona I get 5:13, which really sucks.
I tried to level the playfield and set the displacement to 2 screen pixels for Beta 2 and got 1:31.
The displacement of the latest beta looks a lot better, but the rendertimes are a tad too long. bowl test scene.c4d (284 KB)
Yup, the Windows installer is Windows 10 only. You guys messed up, because there are people using Corona on Windows 7/8/8.1, as well. We need a new installer that supports these operating systems.
Thus said, it’s a bit of a wonky procedure. Sometimes you have to switch on/off effects in the VFB, or dial up/down some values, sometimes the effect flashes on/off like the direction indicator of a car and appears or disappears randomly.
It was more stable with beta 1, with beta 2 it became less reliable and with the latest daily, the old reliabilty has not yet been restored.
Do you have an option to enable/disable it in your installation? For the Max version, it is said to be in “Dev / Experimental Stuff”, but I could not find it in C4D.
So after your PM message, I figured what the issue is and can confirm it - the displacement works in a weird way, indeed. Currently, the displacement always uses UVW mapping, which is wrong of course. Thanks for the report!
