2.6.3 - instanced emitters

Thanks for the update guys, this has sorted out the crash on install and file format issues. However, I'm still having problems with the instanced emitters.

In this very simple scene I've placed a default poly grid at the origin, added a 0.1 poly cube and linked it to a model. I've raised it up and placed a hmi100w emitter material on the cube.

Before we even get into instances I'm noticing a very obvious cross pattern from the emitter. I'm guessing this is from the fact that the emitter is a cube and has faces at 90 degree to each other but I'm sure this pattern wasn't there before.
Image


In this next image I've duplicated (not instanced) the emitter cube model and things seem to be working fine (apart from the cross pattern again!)
Image


Now I've instanced the second model (on the right) and move it to the left of the initial central model. The cube is glowing but it's not casting illumination on the grid below.
Image


Things get even stranger in FIRE! In this screen-grab, the model on the right (which is the one used for instancing the one on the far left) has dimmed and the central emitter is even brighter. It's as though FIRE is placing the right-hand model's emit point at 0,0,0? (This image is exactly the same setup as the image above, just FIRE instead of mxcl).

We know about it and it's a bug in Maxwell. AFAIK it will be fixed for the next update.

Bogdan,

thanks for the prompt reply. Do you mean the next Maxwell Render update i.e. 2.6.1 or the next Softimage plugin update i.e. 2.6.4?

Also, is the cross pattern on the floor grid caused by the cube shaped emitter or is this something new? I don't remember it doing this cross before (although I don't often use free floating purely cubic emitters!)

The instanced emitter issues in FIRE issue will be fixed in the next plug-in update (2.6.4). The production engine has a similar problem, and that will be fixed in Maxwell 2.6.1, we can't fix it from the plug-in. I don't have an ETA for either yet.

The cross pattern looks like a new engine bug. We'll look into it.

Mihnea,

thanks for the updates. Again, glad to hear you're working on this.

Also, thanks for the confirmation of the cross-pattern bug, I certainly don't remember this from last time.

I've checked with the engine guys now, and that cross pattern is an artifact of using a cube as an emitter. It's not new, we've just checked with 2.5 and it renders the same image.

Hi - is the latest plugin available from the download area? 2.6.3?

EDIT: OK, works now.

Sorry, there was a bit of a confusion here. Build 2.6.3 was uploaded to the beta test area and Richard got it from there because he's in the beta group. We were still testing it, so it wasn't available in the main download area. We are making it public now, it should be up in 15 minutes or so.

Thanks for the confirmation about the cross-pattern. I did wonder whether it was the geometry causing the problem. I guess I've just never noticed it before?

Sorry for posting about 2.6.3 beta on this forum, it was more of a continuation about the instanced emitter issue in 2.6.2. I'll try to remember which version needs to be posted on which forum :oops:
