Nice update in trunk today

Great update in trunk today.
Looks like transparent object correctly displays without z sorting issue when camera moves/rotate
Even deferred render receive some lights.
But not sure why transparent is too much transparent. Even alpha is set to 254. Maybe I did it wrongly.
I used:
Code: Select all
IMeshManipulator *manip = device->getSceneManager()->getMeshManipulator();
for (int j = 0; j < mNode->getMaterialCount(); ++j)
{
mNode->getMaterial(j).MaterialType = video::EMT_TRANSPARENT_VERTEX_ALPHA;
for (int k = 0; k < mNode->getMesh()->getMeshBufferCount(); ++k)
{
manip->setVertexColorAlpha(mNode->getMesh()->getMeshBuffer(k), value);
}
}
Any suggestion of how I can make transparent work correctly?
Thanks

Does it change at all when you change the alpha value?

This is a bug in irrRenderer, I think - are you using the "update" branch from my git repo? Transparent materials are still broken
I have seen a similar thing myself, however I haven't fixed it yet.

Yes it does go lighter as alpha becomes smaller.
But there is a big alpha change between 255 and 254.

Yup! your updated branch : ). With slightly changed to the flags.
void scene::ILightManagerCustom::OnPreRender(core::array<ISceneNode*> &lightList)
{
Device->getVideoDriver()->setRenderTarget(RenderTarget, RenderIndices, true, true, false);// , video::SColor(255, 255, 0, 0));
}
void scene::ILightManagerCustom::OnRenderPassPostRender(scene::E_SCENE_NODE_RENDER_PASS renderPass)
{
if (renderPass == scene::ESNRP_SOLID)
{
Device->getVideoDriver()->setRenderTarget(0, 0, true, false, false, 0);
deferred();
Device->getVideoDriver()->setRenderTarget(RenderTarget, RenderIndices, false, false, false, 0);
}
else if (renderPass == scene::ESNRP_TRANSPARENT)
{
Device->getVideoDriver()->setRenderTarget(0, 0, false, false, false, 0);
deferred();
}
}
I see, but from my my test, transparent object does receive the light.
Only just that it is too much alpha transparent : ).

Well, yes, that is what I meant by 'broken'
It is not, in fact, an updated branch, but rather a work in progress 'update' you're not really meant to use
But I'm hoping to fix the transparent materials and merge into master soon-ish

Hehe, I can't wait to use it.
Because I need to somehow trying to fix the directional light issue.As the light dims and also at some angle it turns off. There is clearly issue with the dot product at 90 degree as light = 0.
I think since we have the ambient separately, directional light shader would only work with diffuse component.

Hurray!!
But - do partially-transparent textures work? For me, it seems it's only transparent when the texture is fully transparent.
