It’s an Intel thing. Do you have an Intel processor? Also, it’s a 3.0 thing, I think.
However, you images look exactly the same, to me.
Hi Glorybound,
Yes i have a intel core i7 3820 processor which is support SSE and AVX in the CPU.
According to what i learn from this forum, Vray 2.40.04 user cannot get embree plugin from the following link:
http://help.chaosgroup.com/vray/misc/, after extract the file, copy the vrayembree2013 in the 3ds max plugin folder, because it dont have vrayembree2014 in the folder, but it has been confirm from this forum that you can use vrayembree20133 instead. am i missing anything??
The image look same, but my question is with embree it only increase 1 minute fatser rendering?? not 25% to 30%??
That’s right, I forgot. I haven’t heard much about Embree, so I don’t think that it turned the industry on its side. I do know that it works better than VRay’s core algorithm. People smarter than me will know more and might response with more help.
Thank you and i really hope someone will me to find out how to decrease more render time with embree.
In V-Ray 2.x, Embree will only accelerate static geometry so it’s best to set the default geometry type to “static” in the V-Ray System tab. Since V-Ray 3.1, Embree can accelerate other kinds of geometry too.
Best regards,

Hello,
I guess Embree will show more rendertime speed up for more complicated scenes … here we can see big improvements with our (big) scenes, when it comes to deal with several millions of polys, thousands of objects ! I may be wrong, but TBH, I wouldn’t expect big improvements with a single object shot 
I did set the default geometry type to “static”
quite agree with you, i will try embree again when i work on big scene 
Hi just give some try render with a simple scene with embree, i am using Vray 2.40.04
I have one VrayDomeLight(Subdiv: 32) with HDRI in this scene with the below setting:
Render size: 800px x 600px
Overide mtl: On with Vray Mtl white
AA: 1/6
color mapping: sub-pixel mapping On, Clamp output lecel: 10
Irradiance map: Preset low
Light cache: subdiv: 500
Noise threshold: 0.01
Default geometry: static
Here is result:
No Embree
-------------
Embree Default
------------------
Embree bhv2
----------------
Embree bhv2.spatial
------------------------
Embree bhv4
-----------------
As you can see all the image have anti-aliasing issue and a lot of white spot, and also the render time is a little difference with no embree one.
Continue from previous
Embree bhv4.spatial
-----------------------
As you can see all the image have anti-aliasing issue and a lot of white spot, and also the render time is a little difference with no embree one.
I assume the white spots are because of not enough samples, can you post some Sample rate passes and you can also try with version 2.50.01
You can also post the scene too and we will tell you what are the times with version 3.0.
how to increase samples? is it increase dome light subdiv?
Increasing the Dome-Light subdivisions should help to reduce the white spots noise.
Decreasing Color Threshold value from Image Sampler should help to improve Image Sampler quality.
If the above tips do not help please send us the scene for investigation.
I did notice in the first 2 renderings at the start of the thread that the Embree one has a small white dot that appears in the middle of the seat cushion. not sure if that was a sampling issue as well.
