[Max] I need help! / Re: Fireflies with HDRI

« on: 2018-10-03, 00:50:38 »

As the title suggest, I just can't seem to get rid of fireflies when using an HDRI - never had this issue before, seems to be a Corona 2 issue.  Using 1714 from Peter Guthrie.

The material isn't too reflective and blurring stuff isn't an option.

Anyone else experiencing the same thing - it's almost making HDRI's unusable for me on exteriors

Are you overriding you reflection slot with a different HDR?  Or using the same one for GI and reflection?

Try using Pixamoon gamma script.  It costs $4 but worth it.

Maru registered the issue into the (public) bugtracker. To avoid duplicates, your thread was moved to "resolved".

Has this been resolved though?  I am experiencing the same problem in Corona 2.  Insanely intense fireflies when using a different HDR in the reflection override slot than what I was using in the GI slot. 

...What I did find is that is I use the same HDR in both the GI and the override slot everything renders as expected.  I haven't tested this on any scene besides the current one I am working on.

See attached images.

I have a question...  Why do some prefer to use the viewport IR?   Is there an advantage?  I have always found the floating window to be more powerful and more flexible as I can simply move it to my second monitor without the need to sacrifice the windows of my modeling space.  Is it anything more than personal preference?

That sounds extreme.  Do you have EXR compression turned on in the save dialog?  That would be my first guess.  Second would be that you are rendering to deep EXR but I am not actually sure that is possible with Corona.

[Max] General Discussion / ELI5 Glossy Reflection

« on: 2018-04-12, 17:45:10 »

Explain like I am 5 glossy reflection... 

I recently added a bit of glossiness to my reflection and it made the reflection not behave predictably.  It made the reflection appear as though there was refraction issue with the glass.  After digging around a bit I found out that enabling caustic reflection or enabling this glass option fixes the issue glossy reflection issue.  Can someone shed light on this?  Is this a bug or a feature?  Because it feels like a bug to me.

Keep in mind that this is a marketing video.  It is easy for things to look good when the company if fine tuning for the purpose of making their product look great but that doesn't mean it will translate to real life working environment.

Excited that Corona is getting VFX tools.  Now if they can just fix the huge ram consumption maybe this engine will be able to render more than just nice interiors and houses.  Corona would likely never have a shot at being used for anything more than visualization and product renders going down the path that they were pursuing, now their game has changed.  New tools and a lot more exposure in Hollywood.

[Max] Resolved Bugs / Re: Bloom/Glare doesnt work with Cubemap/Spherical/Cylindrical cameras

« on: 2017-01-17, 21:08:29 »

The solution in the meantime is to add a CShading_Beauty pass to your Render Elements and make sure that "Apply bloom and glare" is unticked. This will give you a pass that you can use to feather out the problematic areas of bloom and glare in post.

This is typical of most render engines.

But..  If you tick the glass not to be visible in masks then the AO pass will ignore the glass and render as expected.  You may run into a problem with refraction of glass as I don't think the passes currently take this into account but I could be wrong.

[Max] I need help! / Re: Corona/max render combined with sketchup linework in post, Camera Problem.

« on: 2017-01-04, 21:31:21 »

Yes i am aware of the knowledge of Alex Hogfrefe. He really does a lot of great tutorials. Also that is the workflow i use too, but than at the moment i use Blender/Cycles for rendering as the cameras match exactly. Alex Hogrefe does it all inside sketchup as for what i can read on his website (vray for sketchup).
But i would love to use corona for it because of the double work by using two different kind of software. Guess it has to do with 3DsMax being the problem.

Just be sure that you are not making things more difficult than they need to be.  The more difficult it is the more likely you are to a failure leading up to a deadline resulting in poor quality or missed dates.

Rely on the K.I.S.S. concept as much as possible.....   Keep It Simple Stupid.

A few years ago I needed to do an exact match to a Rhino camera.  I can't recall the exact workflow but I was able to get a 99-100% accurate match.  I am not sure how SketchUp cameras operate but if I recall correctly Rhino relied greatly on the aspect ratio of the frame.  Changing the aspect ratio changed the film gate / sensor size of the digital camera.   I was able to use a reasonably simple formula to calculate what the resulting sensor size was, and then plug that into Max along with the same focal length and aspect ratio.  This resulted in an exact match as long as no one changed the aspect ratio that was used.

I am not sure any of this helps you with you as I don't use SketchUp but perhaps it will lead you down the path of researching how the SketchUp camera works and how that might be translated to Max.

Please keep us updated on your progress.

This would be useful.  I often do a quick check with Teamviewer on my phone and if I accidentally zoom it is a pain to get the frame buffer back to where I need it to assess the image.

A 1:1 and fit to frame buffer would also be useful.

I think that the problem is still with setting up the longer edge output value. It's limited to around 32 000px in 3ds max.
Do you think that there is any script which could slice that view with cameras or something? Or any other way?

Scripspot likely has a script to help render at this res but if not you can easily render smaller horizontal segments using a horizontal offset in the camera settings and then reassemble in post.
