CORO 6 - Normal map adjusting cause C4D freeze ! R21

Corona Corona for Cinema 4D Issues
1

Reproduction → I setup a material with normal map. Start the interactive rendering, change the normal map intensity value, swap R/G channels or just turn it off and on. Stop interactive rendering, after that it asks do you want to stop current rendering ? Whether i click yes or no c4d freezes. By the way normal map destroys the whole material when i make ANY adjustment on it, so i have to reload the whole scene, simple automatic refreshing doesnt work for that.

Thanks, Lev

Hello,

is it possible to send a snapshot of your node material editor (or Material Editor window) for further examination (or the problematic scene as a whole)? Simple scene with Bitmap > Normal shader > Corona Material did not result in any issues for me when following your steps. If C4D crashes, sending a minidump or a crash log would also be very helpful.

Thank you and sorry for the inconvenience,
Jan

Dear mmarcotic,

Here it is:

Reproduce the freeze: click on bump → normal → lets say tick swap R/G channels (normal map brokes this point so you have to restart VFB) → do you want to stop current rendering → yes → freeze

thanks: Lev

bugreport.txt attached - btw its hard to find a way to report this bug because there is no crash (this time happened thats why i could send this bugreport) but freeze.

If you ever feel the need to end a frozen C4D AND get a bug report, press “left shift”+“right shift”+“del”.

thank you Cinemike i didnt know that :smiley:

Hello again and thanks! I have just managed to reproduce it in your scene. I will dive deeper and then report it to developers.

Thank you again for reporting this,

Hi Devs,
is there any workaround for this problem ?
Really annoying because this problem makes real time material development with normal map basically impossible…

thanks: Lev

Hi Lev, Do you get the same freeze if using the viewport IR?

10

Nope ! That works well.

11

Whats interesting, that the default c4d material doesnt produce this normal map crash… Only the corona material

12

Thanks for confirming.

Hi Levinho, could you also test out the V7 daily build and let me know if the problems persists here as well?

14

i tried yeah, same problem there

Okay, thanks for letting me know. I have logged your report in our bug list.

I hope you can fix it soon… I dont know its something wrong only with my system or other users experience this problem too.
Now, i cant even adjust my materials with normal map, because c4d freezes immeadiately.

thanks, Lev
