Maxwell Render | Official public forum

Hi,

I have persistant issues using the HDR lightstudio plug-in within V3 for OSX.

It is running fine until I render a scene.
Render is going fine, but then I can't return in MX studio. To do that, I have to force HDR LS to quit and then can go back in MX studio.

Then relauching HDR studio, and then reloading the scene.

I asked HDR lightstudio, but they are not doing the encoding for the plug-in

Is anyone of you having the same issues ?

IS there any way to avoid this ?

Thanks in advance

Hi,

Mark here from HDR Light Studio

I think we have already addressed your problem through our support emails and solved your problem I believe.

The issue was when using HDR Light Studio in a live session with Maxwell Studio 3, no file is referenced in the background environment, because when in a live lighting session the HDRI data is provided directly by HDR Light Studio to Maxwell Studio, not via an exposed file on disc to the user.

I think the problem you had is you were trying to render your scene in Maxwell Render from Maxwell Studio, and Maxwell Render crashed. We concluded the problem was trying to render your scene in Maxwell Render when you were in the middle of a live lighting session with HDR Light Studio and using the live HDRI data, not a file on disc.

The problem was resolved by always rendering your HDR Light Studio lighting as a HDRI map on disc which automatically then sets Maxwell Studio to use this file on disc for the environment. If you do this before starting a production render in Maxwell Render, then there is no problem.

It it true would be nice if this was handled more elegantly and didn't create a crash. I will talk with Next Limit and tell them the repro steps and we can work together to look at this.

So ideally, would you like to be able to produce a final production render in Maxwell Render using HDR Light Studio's live lighting HDRI data? So you don't need to render the HDRI map on disc first? This can cause problems because the resolution of the live HDRI lighting from HDR Light Studio is very low. This will produce inferior quality reflections with clearly visible jaggies.

I would always suggest if you are going to the trouble of producing a final render of your Maxwell scene, to render your HDRI map to a good quality HDRI map on disc before starting your Maxwell render.

Mark

Hi Mark,

Yes Indeed, the issue was partially solved but the trick is not working all the time. And we agreed that I should adress this issue to Next limit

Actually, I think your product is great, and I really recommend it ! That's why I would avoid to do those back and forth manipulations (The idea was to create a copy of the HDR map and launching the render from there. As said sometimes ok, sometimes not…)

And the bad thing is after relaunching studio (when it crashes), it doesn't load automatically the HDR LS file. Which forces you to save every steps in multiple format (MXS, HDR, HDI)

Fire is a great help, but very often, you just have to look at a much better picture to check your reflections and materials. That's why the render is important
When tuning the lighting set-up those aspects are critical to avoid post-prod. Doing all those extra manipulations extract you from your creative process…

Hope a patch will come up soon !
