@Reflexus: Are you sure this is a valid indices list for the volumetric lines?

It's not working.

It's not working.

How so? Please explain the problem, as I asked before. I just left you with tips and example code to get you pointed in the right direction -- but it was a guess nevertheless -- because you have not explained the debugging results.

The lines are deformed, it seems that the index buffer is not valid.

So it doesn't have any crashing issues? (edit: Hey, I'm just expecting the worse )

No, nothing more than just deformed lines, you might want to look at the effect file to see how the indices should be like.

Really... If you're not sure how to get them right yourself, just try different combinations. Really. There aren't too many to try. You could have fixed it by now.

Edit: Oh, sorry. I sound sour. I am not able to help you further. My time!

Yes, I have been trying to use different indices but couldn't get it to work.

Anyway, consider the question closed, I'll look for a way to resolve the issue.

To anyone who could have this problem, the question was resolved here:
