Title: Repeat Albedo/diffuse/Color but not alpha ?
Post by: DavidM on July 09, 2021, 03:12:13 AM
Hi,
Is it possible to use an alpha as a mask for a tileable texture?
I don't know how to use the vertex mask painting with your game engine so I wanted to simulate it by creating an alpha map and tile my diffuse map.

But I don't know how to achive this kind of thing or if it is even possible.

If anyone could help that would be great. It is really hard to find any info to create a map, except basic knowledge I find it really difficult to understand how your engine work.

Thanks for anyone that could help me.

Hi,

As far as I know, texture blending is not possible in KRP.

For more info on supported features, please refer to http://docs.piboso.com/wiki/index.php?title=Track_Creation_Guide .

Thanks for the help. This documentation is quite helpful but a little bit confusing sometimes.
Do you know if I can find any spec about the engine ?
The typical tri count for tracks and environment? Same for the texture and texture size ?
Thanks

No worries, mate.

KRP is based on a custom-built OpenGL engine, so http://docs.piboso.com/wiki/index.php?title=Main_Page and some discussions on this forum might be the only source of information.

A general rule for all surfaces and objects - minimise your polycount (otherwise, the FPS rate will suffer) and avoid a double-sided mesh.

Just a quick example, a wireframe view of PiBoSo's Rye House:

Thanks, that really helps.
Is it the track from this video? Do you know if the trees are card or meshes ?

From this video?  ???  Rye House is one of the tracks which come pre-installed with the game. Trees and bushes are low-poly models (like perpendicular rectangles) with alpha-channel textures.

Oups I forgot to past the link  ;D

Thanks for the help about the trees, I'll add some in my map.

By any chance do you know how to use the height feature in Tracked ?
I can edit the height but I'd like to export the modified track in FBX to add some props.

No idea, sorry. I think, heightmaps are more about MXB rather than KRP anyway...
