[Max] I need help! / Corona 1.5 LUT vs ArionFX LUT's

« on: 2016-10-31, 12:20:36 »

The amanmq built in LUTs share the same camera models as many of the ArionFX LUT's, yet they seem to output very different results.  Should the LUTs applied in frame buffer and in PS/Arion on a 32bit EXR be the same/very similar?

I have attached two images below, one with LUT applied in Corona, the other in PS with arion. Both using the a 'Canon DSC 315 #5' LUT

Work in Progress/Tests / Bach on the shore WIP.

« on: 2016-08-28, 14:43:36 »

Project for a 'Photoreal Rendering' unit as part of our Masters of Architecture course.

House designed by myself.

Trying to figure out the best way to achieve the beach environment.. at the moment it's all HDRi..

Exterior shots will require modelling of the ground plane no doubt. Any suggestions welcome!

Will post progress as it progresses..

[Max] I need help! / Beach Scene Help.

« on: 2016-08-25, 09:31:05 »

Hi Guys,

Hoping to create a beach scene similar to this:

Would very much like to stay within Corona and not have to render the ocean out in vray.

Tho, I have read about compatibility issues with Corona and Phoenix FD with animating meshes etc.

The ocean would obviously need to be more than a displacement map.

Anyone had success creating a scene comparable to the video linked here within Corona? If so, what plugins did you use?

Cheers

4th year uni project rendered with Corona.

Mostly modelled in SketchUp and then imported and refined in 3DS.

[Max] I need help! / locating problematic normal map?

« on: 2014-10-20, 16:38:20 »

Hi,

Is there a simple way to find the culprit for the error with standard max bump not working on render?

I have a scene with a heap of assets that came in with all separate materials. I have converted them with material converter, but get the normal map error. Im wondering if there is a way to see easily which object/material has the normal map in question.. (without checking every material!)

Thanks

Gallery / Mesh facade at dusk.

« on: 2014-10-15, 17:39:15 »

Finished the first image of a set.

I created a HDRi map from fisheye photos at the location, as well as took the backplate of this image.

Mesh is all geometry, chewed through 5Gb of Ram alone.

Should be more finished in next week.

[Max] I need help! / ShadowCatcherMTL only receiving self illumination and GI, not direct.

« on: 2014-10-15, 12:30:16 »

Im trying to do a scene where the lights on the inside of the building spill out onto the backplate (the front door is glass) and consequently i need the shadow catcher mat to receive the direct light. I have only had success in seeing the light effect the shadowcatcher plane when i use a box with self illumination, or an object with a strong light near it that bounces GI onto the shadow catcher.

When I use a corona light, even a very strong one, it ONLY effects my 3D elements, and only a tiny amount of this light is visible on the backplate from the indirect bounces.

Objects with a corona light mtl also do not work, again they only effect the 3d elements.

Is there a way to get the real corona lights to illuminate the shadowcatchmtl without it being bounces of an object or being self illumination?

Thanks

[Max] Resolved Bugs / Shadow catcher "For Compositing" mode introducing noise.

« on: 2014-10-13, 10:45:22 »

I'm wanting to use the 'for compositing' mode with the shadow catcher mtl. Ive got the override visibility set to black (backplate bitmap unchecked).

The issue I am getting is that using this mode, it is producing more noise than when the alpha mode is on 'always solid' and the backplate is in the direct visibility override.

The left image has shadow catcher with 'for compositing' alpha mode and you can see the extra noise/fireflies that are appearing. The right image is when alpha mode is 'always solid' and the backplate is in the visibility override.

Both renders are after about 7 passes.

A bit of the backplate is showing on the left image and Im assuming this is just from reflected GI from the 3d objects. With the alpha mask this is all erased so I don't think that is part of the issue.

Not sure if this constitutes a bug but it is definitely the alpha mode in the shadow catcher that is causing this difference.

[Max] Resolved Bugs / Berconwood map offset crash

« on: 2014-10-12, 13:53:27 »

I get an instant max crash on offsetting the 'mapping' of a berconwood map plugged into diffuse of corona material.

Not sure if this is a corona bug, a berconmaps bug or just my computer.

If anyone else tries this and has the same crash let me know.

This is with the 'variance' offset, not transform.

[Max] I need help! / Infinite/Vray Plane Corona equivalent?

« on: 2014-10-12, 09:37:47 »

Is there a way to get an infinite plane like vray plane in corona?

I have tried using vray plane with corona material but this does not work.

Obviously I could make a massive plane and ignore from extents (which is what i have been doing when needed.), but it isn't as easy as a simple infinite plane.

Sorry if there is already such a feature that i have just been missing.

Thanks!

[Max] I need help! / CoronaShadowCatcherMTL + Backplate Help

« on: 2014-09-17, 15:02:55 »

I'm after some help with fitting an object into a photo backplate.

Ive got the backplate setup in my viewport and in the environment map etc. It is showing up fine in the render.

I then set up the ground plane with a shadow catch mtl with the backplate plugged in, this seemed to work too.

The issue I am having is the exposure of the objects. I can't seem to change the exposure of the scene without affecting the exposure of the backplate. Also, is there a way to use photographic exposure without  affecting the exposure of the backplate?

I don't know why but my corona sun and coronasky intensity values have to be at 0.1 to get okay looking results.

If some one could talk me through the proper method for setting this type of thing up, with a backplate and a corona sun + sky for lighting, it would be hugely helpful! thanks.

Work in Progress/Tests / Studio Apartment WIP

« on: 2014-09-08, 11:34:55 »

My arch uni project this semester taking shape.

At the moment still pretty schematic. Resolving over the next few weeks.

Trying to work out materiality and windows etc and corona seems to be the right tool for that!

will upload the progress over next few weeks.

[Max] I need help! / Holl polycarb material help

« on: 2014-08-16, 15:19:22 »

Any suggestions for creating a material like Stevens favourite polycarb?

Im planning on a scene lit mostly through this kind of translucent wall plastic so would have to find a relatively quick to render shader.

Gallery / motion blur birds eye exterior

« on: 2014-05-29, 11:01:55 »

First go with Motion blur in Corona.

The project is my urban furniture assignment for uni.

Render took about 30 minutes at pretty high res.

Grass made by me and scattered with Forest. Trees are ever motion 58.

[Max] General Discussion / Scene Parsing + Ram usage

« on: 2014-04-04, 05:27:47 »

My scene is taking 1 minute 20 seconds to parse the scene. Most of this time the frame buffer and max window are frozen.

Its not a extremely complex scene.. its about 10 different Laubwerk trees with custom corona mats scattered a few hundred times with forest pro 4.15.

The ram usage seems to go steadily up over the 1 min 20s to peak at 15.5gb (I have 16gb Ram).. then drops to about 14.5gb when rendering begins.

Im not sure if its normal, as i dont usually check ram usage when just in max, but having the scene open in max alone is taking up 10gb ram as the only program running. . without rendering.

I guess im just wondering if this slow parsing time and ram usage is normal or if there is something i can do to fix this.

Thanks,

Josh
