I'm a vintage voter also :)

No problem on taking a while to write back, glad it helped that's the main thing!

For question 2, the Output section is the same as in Max's native Bitmap, and information can be found here:

I never head in there except when I am using a bitmap purely as Self Illumination or an HDRI for the environment, where I use the Output value to control the brightness. For a regular material with a bitmap in the Diffuse I never normally need to use those parameters if using a regular PNG, JPG etc.

For question 3, the tooltip pop up describes it well - the value shown in your image 1) is how much the surface reacts to light, while the value shown in 3) is how much the colour from the bitmap is blended with the base color for the diffuse (prior to then being affected by the Level value saying how that final colour will respond to light). So if you have a bitmap, a Diffuse Color of red, a Diffuse value in the Maps rollout of 0.5 then your colour will be a 50% mix between red and the colour from the bitmap image - this resulting colour will then be affected by light in the scene as controlled by the amount set in the Diffuse Level.

Hope this helps!

Sounds like a minidump would be useful! (

At least, for those times when the whole machine doesn't reboot :)

Other thoughts - have you tried painting the whole scene with one simple CoronaMtl and rendering to see if a material is the cause? Or rendering sets of objects to see if a particular object is the cause? Any plugins in use for the scene? Any elements from another render engine left over, if it was a scene converted from another one? Can you share the scene itself (can do that privately if it can't be shared publicly - )


EDIT - other thoughts: what SP of Max 2105, and do the crashes happen with other scenes or just this one?

For a pool, my thought would be to fake it by projecting the caustic pattern using a light - as an example in 3ds Max, add a spotlight, set to rectangular, open the Advanced Effects tab, drop a texture that represents the colours of swimming pool caustics (should be plenty of free ones out there on the web) into the Projector Map box, then to make setting it up easy I'd ensure the walls and floor of the pool are separate objects and use an Include / Exclude list under General Parameters so that the light only affected those.

Hope this helps!

Could be good!

I look forward to seeing them! I like day and night comparison shots so it will be interesting to see!

Hi Yagi,

No further ideas here at the moment, sorry - so far those are the only suggestions I am aware of that could make a difference, and not sure what difference it is that makes this happen for 1 or 2 folks and not everyone else. In this instance, we'll need to wait for Ondra it seems! TY for testing out those possible solutions and reporting the results, all that information is always a help in tracking things down.

They only make blankets and pyjamas, you see :)

TY for sharing the renders! Curious as to why night shots were selected for the project, I can see a mix of night and day, but it is unusual for it to be night only versions.

That works much better, ty! I went with the Gamut node solution. Also I seem to be having no trouble with a 32 bit EXR in Fusion today, not sure what I did to break it yesterday.

Ah that naughty Photoshop! I've never installed any of the EXR handling plugins for it as only just started with EXRs for testing in Fusion, but thought I'd see what Photoshop did to it on open for this thread- sneaky of it to do some conversion without telling me, tsk. I ought to add that in this instance it was a half float 16 bit EXR, as I got those working as expected in Fusion, just in case it is relevant to what the OP is doing.

Not sure what you mean by "3ds Max native render save option" - thinking you may mean save from within the Max VFB?

Anyway, if you save from the Corona VFB (or click and hold Save to open up the Save All if saving multiple passes at once) you will should be getting the expected results (see image attached of the Corona VFB toolbar) and same if saving from a "Save File" setting in the Render Output section in the Common tag under Render Setup dialog.

I did find in Fusion 8 on loading an EXR saved from Corona I had to reapply Gamma 2.2 (in a Brightness / Contrast node) to get the same results as the render, though Photoshop displayed it as expected, but I am no Fusion expert so may have just had a wrong setting on the Loader node :) Just in case it is the application you are opening it in that is making a difference, too.
