Okay, so I've been trying to get a working illumination map working on one of my light entities, but I see to be unable to. I remember being able to do this before though...

For those who know how to do this:

Do I use illuminationent.fx or illuminationmap.fx? What is the difference between the two?

And in order to do this, does my illumination map texture require an alpha channel?

Thanks!

Illuminationent I believe.

See, that's the thing. When I use that, the whole entity appears illuminated, even though I only have a small part of it illuminated in the illumination map. When I use the other effect, nothing happens. Only the Sith deal in absolutes (unnecessary Star Wars reference).

My texture file is Wall Light (Red)_D2.dds and my illumination map is Wall Light (Red)_I.dds.

My FPE



Am I doing something wrong?

No you are not. It is very normal that the shader behaves like that. Try illumnationmap.fx that is what i use for lights. Thought it is illuminated without any actually light there. So make sure you place a actually light.

So both the illumination shaders are broken? I got the shaders working perfectly on stock media, and I did made the FPE for my model based on the STOCK FPE, even tried applying the stock illumination map to my model to see if it would work. For some reason the map just doesn't want to work with my model...any ideas?

Inspire, I've got the exactly the same problem as you. The illumination maps are not working for either shader.

I have an alternate texture for the entity along with an illumination map for it, and it turns black when I switch to it.

some of my selfmade entities also show broken textures and no light fx when using either of the two available shaders. It's terribly buggy.

I am Jacks complete lack of surprise.

illuminationent.fx is for when you don't have a map, it lights the whole thing up. illuminationmap.fx is when you do have a map. because illuminationmap.fx didn't work for me i just color the dark parts of my model black and use illuminationent.fx

Thanks, ZFletch1. Now I know which one to use!

Anybody else have any idea how to get illuminationmap.fx to work? I'm thinking it has to have something to do with alphas, I swear I read that somewhere.

illuminationent.fx is used for dynamic entities.
illuminationmap.fx is used for static entities and segments.

The difference betweent he two is that illuminationmap.fx REQUIRES A LIGHTMAP, meaning it'll be expecting there to be a lightmap passed to it from the engine. If the entity is dynamic, then there won't be one and it'll mess up.

Both shaders require an illumination map texture.

Ensure your illumination map is the same size as your regular texture.


Also of note here, since these are stock shaders, FPSC has a bit of code for them internally. If you give "illuminationent.fx" to a static entity, it will automatically swap it out and use "illuminationmap.fx". So for entities, you're better off using "illuminationent.fx", i mean.... I kinda figured it was obvious that that was what the "ent" stood for in the filename.


Now, for the bad news. I do recall encountering this, and I'm sad to say I don't quite remember what I did to fix it. I was working on the shader system for my mod at the time, but by the end of it all, it was working.

Also, make sure your illumination map texture has the _I suffix.


That's about all I got for ya.


The one and only,

Thank you very much Plystire. I'll double check all these things, but if I buy Project Blue, you're saying you fixed it? Or is that only V1.7?

If it ever was broken, it's fixed now.
