Hi all,
I don't know what's the best tool to use HDRI maps within Corona.
I used VrayHDRI material and it works great.
regards
-
So what's the problem than :- ) That's the best solution right now for those who are also Vray owners. Otherwise it would be clunky 3dsMax bitmap loader instead. Not much else here.
-
And you don't even need to own a Vray (say a converted MR user) just install a Vray trial and you are running
-
Has vray trial an expiration date and does vrayhdri that much better than max's bitmap loader to justify installation of additional plugins? Never used vray, but maybe there is more benefits to have it in 3ds max but not to render with it?
-
I LOVE the Vray HDRI loader. It really has become something I don't like living without. Luckily I don't have to because we use Vray :) But I would like Corona to match it for the commercial release. Just look at the links below to get a sense of what it can offer.
Vray 3.0

Someone know how to resize an hdri map ? i use vrayhdri and in spherical mode there is no way to set the tilling, very annoying
-
I could live with or without but looking at the doc of v3, I have to admit that ground projection seems handy !

i am curious... to what end would you want to tile or resize a spherical hdr image, or how should that work?
cheers,
chris.

Heh, however weird that sounds, it's not a problem :- ) The tiling happens in the rectangular image, so very simple.
But what's the practical use of that, I've got no idea.

I've try to use an hdri map with trees and other things as a background and it appear way too big ..
It's not the right method i know it noww

May be more HDRI of studio with a single softbox than a landscape.
To make the first thumb top left looks more like the top right : https://www.lightmapstore.co.uk/prodimages/hdr_renders_vol1.jpg
I mean, that's the only use I could figure...

hydeman, all you need to do is to put wider lens on your camera, i.e. increase fov or decrease focal length (mm).
-
I think Corona needs its oun HDRI loader...
-
If you use VrayHDRI loader just for the environment maps, and not for example tiled EXRs for displacement, then there is absolutely nothing 3ds Max's native bitmap loader does not have compared to VrayHDRI. Only difference is that VrayHDRI has it concentrated on the one place.
-
vray HDRI has better UI. That is pretty important factor.

Ground projection !

The normal bitmap loader doesn't offer probe projection, I think.

Probe projection? Who use mirror ball made hdr maps anyway? :]
And what is ground projection?
-
Ground projection is in v3, you'll quickly spot it ! http://docs.chaosgroup.com/display/VRAY3/VRayHDRI

hehe... ok! thanks juraj, good to know you were wondering too. i know it would be possible but just didn´t get why one would want to do that...
as mentioned, it would probably be best to try and play with the focal length of the camera as to avoid the close up effect. otherwise... switching backplates for something else? but that might only be an option for things like architectural renderings with lots of foreground going on anyway.
the coolest little thing in corona VS vray for me is that you get alpha channel anyway, even if you don´t override the visibility of the HDR (which you would normally have to do in vray in for example the dome light, ticked to "not visible") - so you get the best of both worlds, i mean you see the HDR background but can choose to dismiss it with a click should you want to.
-
Vray 3 solved that dilema/workaround by giving domelight alphachannel option.
But why that took 10 years is questionable.

ah, yeah! well, good to know juraj, even if this is the corona forum and i am steering off topic. we didn´t make the move to vray 3.0 for some reasons, wanted to hold off till this summer. and with the speed corona is developing at the moment we are quite happy with that, so we will see... are the new shader options for this advanced glossy stuff beyond phong/blinn and so on now part of the vray 3 material shader?
cheers,
chris.

GGX is only part of experimental night build.

Does anyone have problems showing Environment VrayHDRI in the viewport of Max 2016?
Mine draws it pure white, not depending on the multiplier.
Standart Bitmap works ok.

Works fine for me using the latest Vray version. "Overall mult" changes works in the viewport as well. I did have some trouble with that about a week ago, perhaps with the previous Vray version.

I use 3.00.08. Which one do you use?

I use 3.20.02. Try to upgrade to the latest version and see if that helps?

Great!

Can somebody help me? I want to use cylindrical panorama (on corona light) with hdri lighting together, but i cannot exclude panorama object from hdri lighting... That is normal i think :). But how i can do this another way?

Me. To some degree. It´s not about HDR but it´s the projection I need:
For quick´n dirty reflections we usually take a single photo with a circular lens. Take a photo, extend the canvas in PS or whatever application so it meets a mirrorball FOV and plug it into a shader supporting mirrorball projection - ready. No conversion, no stitching, no postwork for the environment at all - just one photo. Enough for reflections when you do e.g. archviz projects where the counterpart is important and would be (and should be) visible in reflections.
Right now VRayHDRI is the only way to do that in Corona afaik, please correct me if I´m wrong. I´d love to see "Mirror ball" in the Environment mode dropdown of CoronaBitmap for this reason in the future.
Good Luck
