A Crash ocures when a Slider is moved
Step1: Create a mesh with a texture
Step2: Add a Convertor - Colorramp to the colorinput of the Defuse Shader
Step3: Add a mapping node to the input of the colorramp
Step4: Add a Texturecoordinate node to the input of the mapping node
Step5: I added a second colorramp between the first colorramp and the Defuse shader because this seams to increases the chance that the error appears. But it's not necessary.
Step6: Change displaymode of 3D View to Material so that the Colors are visible. I'm not sure if that is necessary. It had also once crashed when the mode where set to rendered. I didn't tried it in solidmode.
Step7: Adding some colorpoints to the colorramp and moving them around. Then I closed the nodeeditor and swaped to the properties area on the right where the sliders also are under the materialsettings
After a minute of moving sliders around the crash appeared. Sometimes it crashes just after one second of moving a slider. Once it crashed just after I connected the colorramp to an other node.
This is a Screenshot of the VisualBasic Debugger
Sometimes it is possible to click on Continue and Blender works further like nothing happened.
Otherwise the Error repeats endlessly.
This is my Testfile:
It's only a new File with a rectangular mesh and a texture.
I tried different things to get around this error.
I tried different rendersettings.
I lowered the polrate of my mouse from 1000 to 250.
I tried different graphics drivers.
My first Blender version was 2.68 I think. And I'm not sure when the error first appeared. But I'm sure that it also happened in the last Version witch would have been 2.77
I use Blender also on an other machine. On a minimac with bootcamp and windows 10. The Error never occured there.
I really hope this will be fixed!
