Cannot recolor sprites using legacy API on OpenJK client.

[DaloLorn]

Operating system: Windows 10 Home 64-bit, latest version.

Client type: Multiplayer, but might occur in singleplayer.

Description:

Using the trap_R_SetColor function on 2D sprites (tested with mAutomapPlayerIcon and radarShader) prior to drawing them with trap_R_DrawPic or trap_R_DrawRotatePic2 will fail to change the sprite's color. I'm not experienced enough to track down the core issue, but I'm told that the same function works just fine on procedurally generated icons. (Citation: MB2's block/bodyhit indicators work fine, and those are apparently procedurally generated.)

Initially, I believed it to be an issue with how MB2's code interacted with the OJK client, because I had only witnessed it in MB2 - but last night it occurred to me to test it with base files. Allied players in vanilla JKA should be tinted green (citation: tested on JAMP moments after testing on MB2 and OJK clients). They are as orange as the player himself.

Steps:

1. Run OJK multiplayer client. (Or MB2 client - they're virtually identical anyway.) Use a mod built with the legacy API - I've tested with "MBII" and "base".

2. Start a multiplayer game with more than one player. Bots or dual logging may or may not be required.

3. Get sense 3. (This is perhaps a moot point, as I was unable to sense hostile bots and didn't seem to need sense to see allies.)

4. When another player/bot appears on the minimap, they will be the same color as you.

What was supposed to happen: When another player/bot appears on the minimap, they should be red or green depending on their team.

Pictures?

What is the rgbgen set for the shaders mentioned from MB2?

The difference is clear - allies are supposed to be green, they're white. (Base JKA acts the same way, except it's orange because the untinted image there is orange.)

I'll put up the base comparisons later today.

Shader from JKA - as far as I know, the only modification MB2 makes is to the image itself.
