[Max] General Discussion / Re: Is TextureObjMask compatible with corona?

Oh thanks. This works great! It's a little more complicated to get setup. But it's going to work perfectly.

[Max] General Discussion / Is TextureObjMask compatible with corona?

« on: 2019-09-03, 00:58:03 »

I tried searching but didn't find much. Does anyone know if this is compatible with Corona? Or does Corona have a similar method?
I want to use in animation to reveal as a mask.

So far It doesn't seem to be behaving like I thought it would. But totally possible that I'm not building it out right.

Thanks

Thanks. And am I supposed to use "Real World Map" size in the UVW map? Some materials are hard to tell exactly what size they are supposed to be.

I posted back in Nov 2017 asking if corona materials were available in imperial units and not just metric. I wanted to check back in and see if anything had been done about that. I wish I could use the corona material library as is, without having to go and change my units and save out each material that I want to use. If not, are there any plans to do this? I'm in archviz in US, so I'm required to use imperial.

Thank

[Max] I need help! / Re: Does my isometric look correct & why doesn't camera correct work in this mode?

« on: 2019-03-01, 01:12:30 »

I recreated the camera with standard camera in orthographic mode. I added camera correct modifier.  This again stretched it out so it looks like a correct isometric. But when I render it again changes the way it looks and it's not really an accurate isometric. The walls especially look too short. My pixel aspect is 1.

Any ideas? I require an isometric and it's not working. It basically looks like the same example that I posted. The preview on the right is an isometric, you can see this with the roof and walls. But the rendered on left is not.

Help

[Max] I need help! / Does my isometric look correct & why doesn't camera correct work in this mode?

Hi,
I'm trying to render these construction orthographic isometrics and was needing a little help. I'm using Corona orthographic camera.

1) Does the rendering look correct in terms of being a true 45 degree isometric?
2) I thought the vertical walls seemed a bit squashed. When I turn on the camera correction "automatic vertical tilt" it looks more correct. Although it previews correctly in the window, it doesn't render like that. Why doesn't it render with the til when using orthographic?

Any help please?

Does Corona have a orthographic projection mode now?
A couple years ago I saw that folks said either use a standard camera or play around with camera correction modifier.
I looked but didn't see anything.

[Max] I need help! / Help with outdoor lighting

« on: 2018-12-10, 22:23:37 »

Can someone give me feedback and advice on making this rendering look better?
I'm rendering this metal building that will be used on a web color picker for metal building manufacturer. I'm not that happy with the way this is looking right now. The far right overhead door is blown out and you can't see the panel segments. When I lower the exposure so that I can actually see the individual door panels the scene becomes way too dark.

I'm using a free HDRI map, & corona physical camera. I have reflection override turned on so that clouds are reflected better on wall material. I've set the HDRI bitmap output at 1.5.
In Corona Post I have Exposure at .248. Highlight Compress 1, white balance 65000.

I'm just looking for a bright outdoor scene.
Thanks for any help and advice.

[Max] I need help! / Re: HDRI map reflecting weird with opacity change

« on: 2018-08-29, 23:25:43 »

Thanks for that idea. I'm animating a building with hundreds maybe thousands of parts coming together showing the construction sequence. With something that big how would you go about customizing sequencing of an animated material? Would you have to create hundreds of copies of the material so that the material animates at the desired keyframes? Not sure how one would go about that.

Well when the object is fully opaque I do want it to be affected by the HDRI and have the reelection. It's just the transition part that looks really weird. You get a very odd view of the HDRI map when it's halfway transparent. I guess I could animate the material reflection. But that seems burdensome seeing as I have hundreds of objects that need to be faded in at different times during the animation.  Not even sure what the best practice would be if I went that route. Would I have to create hundreds of variants of the same material?

Thank you for responding.
There is a moment when the object is transitioning from transparent to opaque where there is a weird reflection from the HDRI map. It's not how I want it to look. I've posted in 3dmax forum on reddit and they said it is a Corona issue.
Do you know a way that I can prevent the HDRI map from reflecting like this?

I've slowed the animation down, about halfway you can see what I'm talking about.

[Max] I need help! / HDRI map reflecting weird with opacity change

« on: 2018-08-28, 23:02:51 »

I'm working on arch animations and need to have objects fade in from 0 transparency to 1. I've tried to do this with animating the visibility track and animating the opacity slot in material. Both have a weird reflection of the HDRI map on the object as they transition from transparency. How can I get rid of this? Or is there another way to animate an objects opacity?

Column on the left is animated with visibility track and on the right is opacity slot in material.

[Max] I need help! / Re: Where to put maps when building materials

« on: 2018-08-22, 18:10:22 »

Thanks,
so to use the AOmask. Do you create a blend material. Put main material in slot one and then the AO mask in mask? And use the AO bitmap as occluded color map?

[Max] I need help! / Where to put maps when building materials

« on: 2018-08-22, 02:10:37 »

I know a lot of this is explained in the guides, but some of the maps aren't mentioned. I bought a model from turbosquid. It came with maps for vray. So I'm trying to build it in Corona.

It came with these maps. The ones with question marks I'm not sure where to put.
AO: not necessary in Corona, correct?
BaseColor: ?
Diffuse: put this in Diffuse as bitmap
Glossiness: put this Refl Glossiness
Metallic: ?
Normla: put in bump map as a normal map
Refraction: put in refraction
Roughness: ?
Specular: ?

Can anyone help advise
