Can't control my particle appearence in rendering
« on: August 14, 2015, 08:38:16 PM »
How do I control how particles are rendered in Blender 249b?

I've been fighting this problem for a long time now. I'm trying to use the particle system to simulate debris kicked up off the ground and shrapnel produced from explosions, but I cannot control how these particles are rendered.

They always come out as these large diffuse glowing globs. There seems to be no method of controlling how they appear when rendered.... There seems to be plenty of attention given to how to control how they appear in the work window, but nothing seems to effect how they are actually rendered. I've played with every setting that I can find, and absolutely nothing effects anything in the rendering result. I'm completely out of ideas now.

I cannot figure this out for myself....

thank you very much;

This is the effect I'm looking for - see the pointy speckly appearance of the particles? Whenever I try to do it, they always render out as soft diffuse globs.

I can control how they look in the workspace window, but this has nothing to do with how they appear in Render.... If I set it as points;

It renders as this....

If I set it as crosses;

It still renders out as this....

The same is true with any of the other settings I've tried....

No matter what settings I've selected, it still renders out as this....

I have played with every single button and setting on each of the following panels to no avail. Some of them change the appearence in the work window, but nothing has any effect on how the particles actually render out.

I've searched for help on YouTube and online, but they mostly cover how to produce the particles and such, but not on how to control their appearence. Some talk about these exotic rendering engines like Cycles, etc, but I don't have, or know about them, and am just using the built in renderer for 249b.

All I want to do is render the particles as little specks or points as in the first images rather than those big diffuse glowing balls, yet none of the settings seem to control that....

Thanks,

[Edit]cleaned up the formatting a little. kat

For whatever reason it doesn't appear to be picking up on the particle itself (the actual item its supposed to be rendering), so either one hasn't been set, or Blender is defaulting to a generic 'blob' (over-riding what might be there). What is the emitter actually using as the particle object itself? A texture or an actual mesh object? Beyond that have a read through the following Wiki resources (if you haven't already) to see if there's anything in there that might help.
