BAM Update!
example tables:
- Added new texture Map with Specular / Height / Reflections
How it works:
New texture map have 3 colors (RGB).
Red = Specular
Texture/Objects on table have param: shinnes. This part is used to modulate "shinnes" on texture. So You can make some parts more "shinning" other less. See example tables. Inside You will find textures.
If You don't want to change default "shinnig" for used texture, Red value = 255.
Green = Height
Points on texture surface can be some distance inside it. If BAM have Height/Distance Map for pixels on texture, it can calculate small paralax/relief effect.
To calc position of pixel 2 more values are used:
- Depth Scale
- Depth Bias
This is little complicated to explain. You should try to manipulate it.
Where are that values?
I can only read texture Name, so i put it inside. Here is naming convetion for this new texture map type.
MainTextureName-[DepthScale|DepthBias]-SpHeMap
examples:
We have main texture (ordinary texture) - Diffuse: "Tex1"
In
FP You have to set name to this texture "Tex1-ColorMap"
("Tex1" - You can change, but "-ColorMap" is used to recognize textures)
Texture with normal maps in
FP have name "Tex1-NormalMap"
New texture with Specular/Height/Reflection Maps name is: "Tex1-[0.6]-SpHeMap"
- it will set "Depth Scale" = 0.6
- because there is no "Depth Bias", BAM will use default value (=0.0)
If You want set "Depth Bias" to -0.2 this name will be:
"Tex1-[0.6|-0.2]-SpHeMap"
Caps are important.
How to find right values to Yours textures?
In BAM i add new Menu: [Config]->[Rendering Engine]->[DEV options]
Here You will find:
- "Texture name" - You can choose texture to manipulate, You will have here only textures with SpHeMap
- "Depth scale" & "Depth bias" - here are values, You can try and see realtime effects
You should remember this values and enter it as "name" of this special texture
If You try to add new Height Map texture You can set it name without values: "Tex1-SpHeMap". This way You will have default values (zero).
If You think it is complicate, run my "example" table in "non arcade" mode, press F11 and move camera over table, see effects and play with that values
------------
Blue = Reflection
I create it only for playfield texture.
If You set Blue=255 on all surface. All reflections on surface will be same, as You know. But You can change it on any part of playfield texture. For example If You see "Glossines" for table to max, and paint "blue square", only blue square will reflect table object. If You set Blue=0 on rest of playfield, there will be no reflections.
Notices.
All values R/G/B You should read as separate values. To work with it i create 3 separate layers in paintNet, draw Red on one, Green on second .... and Combine layer by adding values.
If You save it to format like jpg remember, that some colors will be blended.
You can't use Specular/Height/Reflection Map without Normal Map. So You need all 3 types of textures.
You don't have to use textures with same resolution for all Maps.
Here is posible scenario: I want only on existing table create "mirror" square surface to have nice reflections on some part and completly remove all reflections on rest:
1. Change name of playfield texture to "playfield-ColorMap"
2. Create 1x1 pixel texture for normal map and paint on blue pixel (RGB = 0, 0, 255)
3. Add normal map texture to
FP and set name to "playfield-NormalMap".
4. Create texture for Specular/Height/Reflection:
- Load playfield texture editor (like paintNET)
- add new Layer (it will be transparent) - fill it with black color (RGB = 0,0,0) and disable it
- add new Layer (it will be Yours "Blue" texture).
- paint "mirror" surface with blue color (RGB = 0,0, 255), You can blure it or do more nice gradients. But use only blue color
- Remove first Layer (we don't need playfield on this texture)
- Change layers combination for last texture to "Additive" (in paintNet - F4)
- Enable "black layer"
- merge layer
You will have only "blue" drawning on black texture.
I know this tutorial is sily, but You should now see how to add "Red" layer with Specular Map and "Green" Layer with Height Map.
5. Add new texture with Your new "reflection" map to
FP and set it name "playfield-SpHeMap" (You don't have to set params for height map, because You don't use it).
6. Add to table "surface" (outside table)
- uncheck "Render object (Initial Value)" (we don't want to see this surface in game)
- add to surface "playfield-NormalMap" as Top Texture
- add to surface "playfield-SpHeMap" as Side Texture
Thats all.
One more notice. If You change name of texture (
FP : Table - Texture Manager ), You have to assign it again to object. So If You change params for "Hegiht" map You will have to again asign it to surface.
And one more...
Creating of "surface" is important.
FP don't load to gfx card unused textures. If You don't assign this textures to "surface" BAM will not have access to it.

I realy like to make video with new "features" but my desktop/cab computer "die" today. Probably it is power supply
. I have to fix it.
