Custom glowing material

Hi here,

 

I wanted to know what values I needed to input to create a custom glowing white material using DEFINE MATERIAL with the 6 type. I tried the values below and I can't get none to work.

 

1, 0, 0 ! Red
0, 1, 0 ! Yellow
0, 0, 1 ! Majenta

0, 1, 1 ! Pink
1, 0, 1 ! Majenta
1, 1, 0	! Yellow

0, 0, 0 ! Red
1, 1, 1 ! Pink

 

When I use a glowing material from the library, it shows as a cyan color and glow well when rendering. Any idea ?

The GDL docs are a bit "wrong" about this. Type 6 is not actually a "glowing" material. I would rather call it an emissive material.

That wording might still be misleading, but here's the deal: Only in the rendering we can have actual glowing materials, and in the hardware accelerated 3D view (ex OpenGL) we can't even have emissive materials (like type 6).

Instead, what you defined there is this:

In that image the surfaces have their emission colors set to black, red, and white.

 

So if you want to define a glowing material, it will be render only, and secondly you'd need to do it with the so called "additional_data" setup.

I've just discovered that this function IS BROKEN (!).

Given the current state not really a surprise.

Anyway, the true reason why you couldn't get it to work is simple: It doesn't work anymore. Emissive materials will not work like in the screenshot from the official help.

I've sent a bug report. Let's see when or if it ever get fixed....

Ok, I'm reassured because I had made some tries before starting the thread and all my materials were glowing red so I thought the issue was from my software. The only time I managed to have a glowing white was from using a material with a proper luminance channel from the surface manager

Hi,

 

Is there any news on this ?

No. Local support said it's not a bug and it "never worked" (????) in the first place.

So yeah, it will never get fixed.

Might wanna try your local support, too.
