Did I miss something, or does SetObjectMeshCastShadow not work? And is SetObjectMeshReceiveShadow not a command at all??

Those commands don't exists. Try SetObjectCastShadow() SetObjectReceiveShadow()

Well it works in classic, or at least the cast shadow one does.

Go try it.

Well.....it doesn't work, that's the point - but its recognised as a command and has the syntax requirements in.

Yes. I see that now. It is not mentioned in the documentation. Maybe it's something they intend to implement but haven't fully done that yet

SetObjectMeshCastShadow is an AppGameKit Studio only command.
The command does nothing in AppGameKit Classic, but is there so that AppGameKit Classic and AppGameKit Studio can both compile the same code.

Source: Wrapper.cpp

Also, setting a mesh invisible leaves it still casting a shadow.

Though I don't expect this or anything else in classic to get fixed now......which would be fine, is Studio actually was compatible with shaders that worked in Classic.

I noticed this as well but it's really handy if you have a complex mesh for the object and a simple mesh for the shadow.
For example a vehicle would be a complex mesh and then you would have a simple plane to cast the shadow (which would be invisible)

That's why it's kinda crucial that the shadow command works.

I got round ot with multiple renders, but if its functional in Studio then its bound to be a super quick fix.

You can turn shadows off using SetObjectCastShadow(obj, 0)

Well obviously....but I want to be able to control shadows per mesh, it's kinda integral to what I have set up.

So you just want to be able to control shadows by mesh rather than turning shadows off when an object is not visible

No, I want different meshes visible at different times, which works for what I am doing, but without having to turn off shadows for the entire object.

Like I said, I got round it but it would he great if these commands worked properly. At the moment you can make a single mesh invisible, but it still renders shadows unless you turn them off for the entire object, where it should only render shadows for visible meshes.

If shadows turned off when and object was not visible. How would you optimize the polygons used to draw shadows?

I dont follow. What do you mean how would you optimise the polygons for the shadows? You've lost me.

If i have a vehicle that is say 2k polygons. It basically has a foot print that is a rectangle. Rather that using the 2k model to cast a shadow i can use a 2 poly plane to cast a shadow. Very similar to LOD optimization.
You can see this is real time using GetShadowPolygonsDrawn()

Found another thing - if you turn collision off for an object, then turn collision back on for individual meshes, it doesn't work - it appears the object setting for collision overrides anything for meshes. Not sure if by design or not.

This isn't the same setup as shadows.

not sure if this is the issue
but if your talking physics collisions object settings do override them and the physics collision needs to be setup again
it probably isnt the issue but i wonder if setting the collision again after turning it back on helps regardless what type
of collision system you use

Thanks Fubarpk,

It's not physics objects or collisions, just regular old collisions. So if you have an object with two meshes, and turn object collision off, than turn back on collision for one of the meshes.....it wont work. Turning collission back on for the object does then make it work again. So you can switch off an individual mesh I guess, but that's just more of a pain to track when your object gets to double digit meshes.

Another odd thing.....setting alpha masking on doesnt appear work when using a custom shader, which means that for shadows anything with a custom shader doesnt seem to allow for this?
