Title: Constant crash A6.3 (Material editor)
Post by: Beanzvision on 2017-03-28, 01:32:34

Attached is a screen shot of the settings prior to crashing. Every time I replicate it I get the same result. I'm using a distorter filter in the Diffuse, Reflection and Bump channels. It seems to only crash when changing settings in the bump. In the distorter settings there are some options to change the type from "Directional, Bidirectional and Flow field". If i set flow field on all activated settings (diffuse, reflection and bump) I get a delayed crash of about 3 secs after engaging it. Directional and Bidirectional are fine.

The problem is the Corona_output with the use of flow field in bump. In flow field the distortion value is determined by evaluating the flow direction of the distortion texture and then the flow direction vector is used to offset the sample coordinate of the texture. With corona_output the flow field function is unable to evaluate the flow direction and cant feed the bump. No more crashes putting corona_output under c4d_filter shader. So distorter->filter (in both texture and distorter channels)->corona_output->texture.

Hi, Much appreciate your detailed response on the topic. I was unaware of this. I shall be making those adjustments!

I don't seem to be getting any crash from this anymore. Can any of the reporting guys confirm this, please?
