MuzzleFlash not working properly in 2.42

[Pixel Perfect]

This was working properly in 2.31 but since moving to 2.42 now appears not to be. I get the same result whether using Framewerk or Framework. The muzzleflash texture does not appear to be masked correctly against the main world although works correctly against the background world. It almost looks like the plane is getting lit although lighting is set to off in the mat file.

 

example mat file:

 

texture0="abstract::muzzleflash.dds"
zsort=1
blend=LIGHT
depthmask=0
castshadows=0
lighting=0

shader="abstract::mesh_diffuse.vert","abstract::mesh_diffuse.frag"

 

 

Rendered against Background:

 

 

 

Rendered against Foreground:

 

 

Do I need to do something different in the mat file now or is this a bug?

I had the same problem, turned out to be a parenting issue, parenting worked for me in 2.31 but from 2.32 on did not. In the end I had to add an MF bone to the weapon and then continually reposition the MF plane to the bones pos/rot values to remove the parenting (pain in the "sitting muscle") to allow the MF to be rendered in the correct world with proper blending.

Thanks MG, I'll look into this (I'm pretty sure I have it parented to a bone in the weapon currently).

 

A pain in the "sitting muscle" is exactly what this is and another classic example of why I hate upgrading to any newer version of Leadwerks Engine as something like this always happens and we are forced to spend time we really can't afford reworking code that worked perfectly well beforehand for seemingly no gain at all.

 

[EDIT]I have confirmed (as you suggested MG) that if I simply position the plane in the right position rather than have it parented to the weapon then it renders correctly.

 

This is clearly a bug and I'll log it now.

I updated all my muzzleFlash code last night both for the player and NPCs to cut the parenting out. It's all working fine now so many thanks MG for the pointer on this
