In much post processing the original view or subsequent views are blended with a view or views that are processed. Such as in a multipass bloom effect.

However it seems that currently if a bitmap is assigned to the camera view, for later processing, view entities will not appear.

The code below uses the workshop emboss example modified with a blob view entity and two lines that set up a bitmap for the camera view. As is, the view entity appears, but uncomment the lines to create the camera bitmap, and the view entity is not rendered.

Code:
ENTITY* blob =
{
  type = "blob.mdl";
  flags2 = SHOW;  
  x = 150; 
  y = 35; 
}
 
BMAP* camera_scene;
 
MATERIAL* mtlEmboss = {effect = "pp_emboss.fx"; }
VIEW* viewEmboss = {material = mtlEmboss; flags = PROCESS_TARGET;}
 
function main()
{
  //camera_scene = bmap_createblack(screen_size.x, screen_size.y,32);
  //camera.bmap = camera_scene; 
 
  camera.stage = viewEmboss;
  level_load("");
  ent_create("blob.mdl",vector(150,0,0),NULL);
}


This is also the reason why a user of shade-c's DOF, HDR or bloom effect find that their view entities are no longer visible with any of shade-c's effects enabled.



Not two, not one.
