[Max] General Discussion / GearVR 360 panorama best practice

« on: 2016-08-11, 18:54:08 »

I tried making a 360 render for the GearVR with Corona, but I put the headset on and it did not look right. I was wondering if anybody did this successfully and what setting they used?

I applied the camera modifier, the projection type is spherical.

The spherical VR mod is on. 70mm for eye separation (GearVR IPD) and focal point for eye converge distance.

Any help or best practices would be appreciated.

Your statement is inaccurate, this only makes sense for fluorescent lights. 3ds (or Revit?) max provides a check mark for this (dimming light changes color temperature).

For LEDs and halogen lights, there is no relationship between a change in light intensity and a change in color temperature. Only a small subset of lamps (fluorescent) do this, so it's almost irrelevant, especially since fluorescent can't dim.

I fixed it by saving the scene before converting...

That's weird. I used the converter (1.26) with no problem. Now I try to use it on a similar scene but nothing happens and the materials do not get translated.

All the options are at default, this is what the listener says:
INFO: Converting scene materials...
INFO: Material conversion took 0.006 seconds
INFO: Iterations: 1, converted: 1
INFO: Converting scene maps...
Autodesk_Map
INFO: Map conversion took 0.002 seconds
INFO: Iterations: 1, converted: 1
INFO: Converting scene lights...
INFO: Light conversion took 0.022 seconds
INFO: Iterations: 11
Conversion done.

When I render, everything is an error message pointing to an Autodesk material. I did not have the problem doing the same thing earlier today.

Any thoughts? I am converting an imported FBX of the Revit sample scene house.

Another thing I noticed is that I am unable to click on the links in the translator: Things to check after conversion, etc

Thanks Romulus! I will try again an wait longer next time.

OOps, I pressed Stop, but nothing happened and CPU utilization was still 99%.

The initial part of the render stops really early if I put in 5 minutes as well. Here is an image.

I've tried baking textures with Corona, but I am getting a few errors.

The progressive render seems to stop very quickly, so the quality of the image stops getting better. The time limits are not respected, so it seems to render forever and I have not been able to render a final image yet.

Any baking tips are appreciated.

I've attached my settings

It'd be great to get baking as only MR and Vray can do it right now... Not a lot of options out there.

[Max] I need help! / Re: Converting photometric lighting to Corona lights

Hi Deadclown,

I am looking for a converting solution. I work with Revit, so it imports my latest lighting designs into 3ds Max (150+ lights at a time). I would not be able to convert all the lights manually.

If Corona could read the geometry information of the photometric light shapes, that would work as well and save an extra step.

I've made a test file for you and discovered a few weird things. The Photometric rectangle seems to be divided is a 8x8 grid, my previous render must've been using a cylinder. The lights were all at 1500 lumen, but the Corona light rendered much brighter.

Regarding IES file shapes of photometric files, the sometimes use a code for shapes that is read by some photometric software (AGI32, etc). So some IES lights want to be rectangles or circles, not just points. Then again, the IES file format is know to be totally inadequate for near-field photometry. We'll need to move onto light-fields for true accuracy.

LM-74-05 is a good document to read if you're really going to dig into IES files. www.ies.org/store/product/standard-file-format-for-the-electronic-transfer-of-luminaire-component-data-1091.cfm

I am using 3ds Max to link a Revit file, so it provides me with up tp date photometric lights.

The Material and Light converter does not (seem to) convert Photometric lights to Corona lights and support has been touted for photometric lights. However, I am finding that linear or rectangular photometric lights do not emit in a linear fashion.



Would it be possible to fully quickly convert these to Corona Lights?

Render to texture / light baking would be a godsend. We still have to use Mental Ray or Vray to do this >:( and it's terrible compared to this engine.
