|Summary||0005682: Problems with particle preview|
|Description||DR generally tries to show previews of particles in camera view, but this preview often doesn’t show up or doesn’t look much like the particle. It’s also prone to rendering issues such as that the transparent textures become opaque when selected, or that other transparent textures behind or in front of it are obscured even if the preview itself seems to be invisible. In orthoview, the preview often increases the bounds considerably beyond the func_emitter itself.|
There was some discussion of these issues in the DR forums, with the general consensus being that particle previews aren’t that useful in non-lighting mode, so may be best to disable them. Personally to me it looks like the same pros/cons exist in lighting mode, too, so maybe entities should generally not show previews of particles anymore?
|Tags||No tags attached.|
|I've removed the wireframe rendering for selected particle emitters, so all the particle quads don't get rendered all over the place. This is how it looks like in non-lighting cam preview, I hope this does the trick?|
That's looking good ^
Admittedly this was a multi-issue ticket since that forum thread highlighted quite a few issues with particles, and there was a general mood that particle previews aren't that useful in non-lighting mode. But I think properly working particle previews would be great.
Here's another image showing another of the issues mentioned, which is that particle previews can obstruct rendering of transparent surfaces such as water.
In this case, the dustfog1 particle is blotting out the water_clear surface. There's no sign of the fog particle itself.
Note that this was made on a PC with an AMD graphics card.
|Has this screenshot been made with the 2.13.0 sources?|
No, that's still DR 2.13pre3. I should look into getting setup for compiling latest DR, too.
You can always grab a portable snapshot build from the Github actions page: https://github.com/codereader/DarkRadiant/runs/3274515207
(There's the Artifacts dropdown on the top right where you can download a portable package). You have to be signed in though.
Alright, that's let me confirm that the issue shown in the previous screenshot no longer persists, thanks! Foggy watery areas will be easier to handle.
Got a small regression to report though: in DR 2.13pre3, the bounds of a func_emitter with tdm_dustfog1.prt measure 24x24x24 units (so just the emitter box), but in build 0000178 it's 547x423x375 units, so including the whole particle bounds. This makes it more difficult to rotate without changing its origin without the correct settings. It's also odd considering I can't see any particle preview for this particle in the Camera.
Would probably be worth it to open a new ticket for this?
