CORO 6 - Normal map adjusting cause C4D freeze ! R21

[levinho]

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 :)

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?

[levinho]

Nope ! That works well.

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

[Beanzvision]

Nope ! That works well.

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?
