casting shadows with fx and v1.12.11

Post by loath »

hey paroj,

this mentions getting shadows to work with the particle fx plugin:
https://www.ogre3d.org/2021/02/12/ogre-1-12-11-released

are these the changes needed? (or am i missing something?)

thanks!

for some reason, i had mShadowCasterRenderBackFaces set to true and my custom particles (based loosely on fx) were not showing shadows. turning off render back faces fixes the issue though.

thanks!

yes, the last change in that series addressed culling:

you could also disable backface-culling on particles altogether..

super easy to upgrade ogre these days. it only took 20 minutes to switch to 1.12.12.

for some reason my particles are shadowing even if i set the mCastShadows = false in the movable. does the render group override a movable's mCastShadows setting? (note this happened prior to upgrade and is most likely my code, just need to figure out what i'm doing wrong)

i will also try this, thanks!

no, that should be sufficient. The render group setting mostly affect shadow receiving.
