@jcl: Right, I was pretty sure they looked a little different in previous versions, but they don't, so sorry for that. 3D BEAM (/ STREAK?) particles seem to be a little darker, though: When I write a loop in partice_trail.c with "particle_mode = 2*key_space", the brightness of the particles changes when I press space.

The brightness is differently calculated in 2D and 3D mode. We tried to make the resulting brightness as similar as possible, but there can be a minor difference in some situations.

here is my simple terrain deformer demo

features are displayed, but you can: raise a vertex closest to the red cube by left click, update terrain hull by U, update hull and set custom normals by F, test terrain hull by a movable character T, move character by WASD, camera is a simple RTS styled one, remove character by pressing T again.

in the main script you can also select loading a wmb instead of created terrain, or not to create water, and also there are some models and map entities which can be created, all by simply uncommenting some lines. but behaviour is the same.

Thanks! This should be a great help for finding the bugs.

as I see there is a problem also with common decal shadows when mirrorwater and terraintex are applied for water and ground terrains respectively.
you can check it in my preload_mode-animation problem-demo if comment lines 168 (my.shadow = ent_unitshadow_rot;), 230 (preload_mode = 3+4+8;), and 240 (shadow_stencil = 1;) linked at another thread.

Why when i use two c_trace in this version my frame rate Decreased to 25-27

Hi,

Can you post a code? I use physX, shader and c_trace and my frame rate doesn't decrease.

Best regards.

I think there is a problem in c_trace

When I write code like this : c_trace(my.x,vector(my.x,my.y,my.z - 4000),IGNORE_ME|IGNORE_PASSABLE|USE_POLYGON|USE_BOX);

game fps decreased

But when i delete this "USE_POLYGON|USE_BOX"
the FPS be good

Why !!

You should either use USE_POLYGON or USE_BOX, not both at the same time (read the manual why). Try and report please.

i use "USE_BOX" but the same probleme
