Firstly, I was so appreciated that I found Robert post the gl3 version of VR kit. I put the link below for anyone want to have fun.

So I made a VR patch which contains some cubes (created with gl.multiple)and a point Floor . Then I tried to applied the Bloom-hq FX 

In normal condition (not in VR）I used to apply the gl.pass fx on single object by giving different gl.node name, then i use a jit.gl.pix to combine the textures together.

Like the following patch. I'm not sure if it is correct way .

jit.gl.pix

jit.pwindow

jit.gl.pass

jit.gl.videoplane

jit.gl.node

jit.gl.gridshape

message

inlet

jit.anim.drive

jit.gl.camera

attrui

jit.gl.light

jit.fpsgui

toggle

jit.world

When it comes to the VR package. I found that I cannot do it anymore. 

1. I have to use gl.pass to output texture to the p_capture_ scene. Otherwise I can't see any FX through my VR OCULUS QUEST 2 ,even the gl.videoplane shows the FX exists.

2.The patch below shows how a bloom-hq fx is applied to all object. But, it's still far from adding FX to cubes only.

3. I tried to capture the cubes and Points seperately and use gl.pix to blend them together, but the VR tracking will be lost and has some view error.

jit.gl.pbr

jit.slide

jit.op.*

loadbang

jit.matrix

vexpr

jit.gl.plato

jit.gl.material

So I'm really curious to know how FX could be applied to single object correctly and how things work in VR environment。

I'm using max 8.5.1 and glcore with Oculus quest 2.

There are things different. 
1. I have to  use  gl.pass to output texture to the p_capture_ scene.   Otherwise I can't see any FX through my  VR OCULUS  QUEST 2 ,even the gl.videoplane shows the FX exists.

2.The patch below shows how a bloom-hq  fx is applied to all object. But,  it's still far from adding FX to cubes only.

3. I tried to capture the cubes and Points seperately and use gl.pix to blend them together, but the VR tracking will be lost and has some view error.

For the record, we solved this on Discord. 

The solution was to use the alpha value to decide which objects would be affected by the passes.

Could you post a link to the Discord solution?

Hi Federico,
Could you post a link to the Discord solution?
thanks Ian


Thanks Federico-- in Max 8.5.1 I'm getting 'vr- no such object'...

ok-- got it ....


I'm having very poor performances here (patch running @1 fps on a RTX 2080 !) , and some error messages 

that's because vr is supposed to be connected to a jit.gl.node, and in this patch it is connected to a gl.pass...

jit.gl.gridshape: jit_gl_geometry_draw_buffers: GL Error: Invalid operation

can you run this patch without error with glcore in Max 8.5.1 ?

Thanks for sharing this patch.

I also get

from jit.gl.gridshape in p tracking.

yes, the patch runs with 8.5.1 without error on my laptop(mac intel)

the p tracking is delivered in the VR package without any modify.

How gl.pass applied to single object and how it works in VR (gl3) ??
