WorldShadows not work

[Wladek]

WorldShadows(#PB_Shadow_Modulative) - make artefacts when load robot.mesh
WorldShadows(#PB_Shadow_TextureAdditive) - do nothink

still

[Wladek]

someone fix it?

[Fred]

If there is no answer, it's because there is no solution yet.

[Wladek]

If there is no answer, it's because there is no solution yet.

when you create solution ?

[PMV]

You are not the only one who waits for fixes. Just wait.
Thats all you will get as answer, as there is no specific
date for any future bugfix.

Wich Version ? Snippet ?

[Fred]

Any chances ?

[Bananenfreak]

In my Project, I wanted to Switch to #Additive shadows, but there are no shadows.

I think it´s a terrainproblem (But only a terrainproblem? I don´t know ).
Try our given example TerrainShadow.pb and Change shadowtype to #TextureAdditive. On my PC, I can´t see any shadow.
I´m searching for a example with not-working #Additive shadows (My Project is too big for it.).

[Bananenfreak]

I don´t know if it´s modified by myself or the original Version of TerrainPhysics.pb.
Here shadowtype #Modulative isn´t working correct:

@Wladek
Without code it's a bit of a guessing game.
#PB_Shadow_TextureAdditive requires you to use EntityRenderMode(#Entity, 0) to allow entities to receive the shadows.
I talk about it a bit in this topic. http://www.purebasic.fr/english/viewtop ... 9&start=15

As for #PB_Shadow_Modulative I'm guessing your talking about "shadow acne".
Not much can be done about that until we can use our own shadow shaders or have the default ones improved.

@Bananenfreak
For the additive shadows I think it's related to the shaders that the terrain system uses, but I'm not a hundred percent sure.
I might be able to dig something up later.

[Psychophanta]

This bug is still visible in the examples from the original PB package. No snippets are necessary to show it. The native examples hang when runned because of the WorldShadows() command; remarking it the examples run fine.
It is reported also in at least:
viewtopic.php?f=4&t=70083&p=517668
and
viewtopic.php?f=4&t=69182&p=511937
