Hello,

I am new to enGrid and have been working through the tutorials. "A" faces are green like they should be but "B" faces are black. This seems to be the case for all the STL and EGC files in the tutorial.

The colors under Tool>Configure>Colours are set correctly. Changing the "A" colors has an effect but changing "B" does not.

I am using 1.4 on ubuntu 12.10. I followed this tutorial to install: https://github.com/enGits/engrid/wik...D-Installation.

Thanks!

Hi,

I have seen this before and it turned out to be an issue with the graphics driver.

What graphics adapter do you have an which driver are you using?

Cheers,
Oliver

Changing the video driver from nouveau to nvidea fixed the problem.

I have attached some relevant information for reference below.

Thanks.
