Visualisation bug in RTP mode while planet rotation

Denis Sirenko · December 10, 2019, 04:05:18 AM

Hi all!

Faced the problem of displaying the new position of the planet during rotation, focusing on its texture. In RTP mode. After turning RTP off and on again, the texture is correctly positioned again. Thus, if I need to search for the desired angle of planet in RTP mode, after each change of parameters, it is necessary to turn off and then turn on RTP again. It seemed to me that after rotation before switching off the RTP mode, the texture moves to an angle two times larger than the one that is correct. Just wanted to share this in the hope that in the future the developers will fix it.

I have not tested if the same thing happens on other objects.

I feel this may be normal behavior. The RTP doesn't handle displacement unless re-rendered, so I can't imagine texture coordinates being correct for RTP when rotating the planet.

Yes, I believe WAS is correct. This is not so much a bug as a feature limitation, and it's one we do need to correct. The overall goal of implementing a way for displacement to be computed and updated while using RTP is definitely something we have on our to-do list.

Understood.

It just baffled me a little that the texture still rotates, and does it in the right direction, and even at a similar angle. The difference is only in the exact value of the angle of rotation. So it looks like working functionality... well, almost working. If it's on your to-do list, then I'm calm, thanks!
