vray and corona

[vlado]

but back the point, will the denoiser work if i say use the progressive sampler type and stop the render myself at a point without setting a time limit etc?

Of course it will work, why wouldn't it?

just asking, but fantastic!

[vlado]

And what exactly are you debating?

For the moment, it seems to be people trying to come up with reasons why Corona is better than V-Ray and me trying to prove why they are wrong Specifically for things like GI calculations, the two engines are very close. Corona is a good engine, there are definitely some good ideas there, but V-Ray can do the job very well too.

Hehe, the only thing i like about Corona is their interactive render, but I guess you guys are already working on it, other than that i always had better results with Vray on the CPU side of things.

[vlado]

Yes, we are working on the interactive part...

i do agree that it seems alot has changed for corona and vray over the past few months, especially with the new vray but i know that for me it was easier to setup and get realistic results faster using corona in interiors, its the reason why many people even use it, wish some other corona users who use vray also would comment but hey, seems its better to keep silent, but there is something there. Another thing Vlado, will there be something similar to the camera controls in corona where you can adjust the iso, fstop etc in the VFB without using RT? its much easier sometimes to do this than guess with real photo values which sometimes don't work for each scene

I think the only way this can be solved is through an old fashioned fight to the death like in anchorman. Lets get chaos, corona and the arnold team to meet up in the square outside the cafe de zaak at eue and whoever's standing at the end is the best renderer.

lol, no, why?
I like Ondrej and Adam, i don't want to fight them!
Compete, heck yes, but fight? :P

Nope, not for the moment; there is only the exposure settings in the VFB.

Yes, and that seems very strange right now

If your solution is to give them on/off one click engine that is fine, it would be understandable why would you stand your ground and explain certain scenario why is something slower or not, it has to do something with internals and it wouldn't relate to end user input...

But Vray isn't about that nor it's slower right now, it is about possibility to tweak lots of things for performance or other needs.

Of course you want usability from render engine. Right now default settings are pretty much ideal for lots of things and that is going in "right" direction, but they are not ideal for every situation, especially if scene setup is wrong.

Industry is watered down right now, too many "experts"... People started to blame everything on render engines, wrong light setups, modeling, texturing, shading and not knowing anything about photography. It seems all those are newly developed render engine problems, but in fact they are not and are older than vray.

Maybe render elements that will tell people how should they fix their scene, pass for instant learning proper light setup, camera control and shading will be nice solution... That would help alot and vray would be even more popular, but i do not believe such thing is possible.

Either lots of people have broken, slower version of vray or few people have faster fully functional version. And that is the main problem here, inability to operate machinery effectively. How else can this 8 page trial be explained. Why it's working selectively?

There is surely a part of user knowledge at play, and yet, part of a toolset's tasks is to guide even the least experienced users towards the right results, so there's surely room to improve in some of the V-Ray bits, and we're working proactively on that (see the sp3 approach to rendering, able to minimise oversampling, historically one of the chief reasons for slow renders with V-Ray, or the default UI, which now needs hardly to be touched to get exact, quick renders. More's cooking.).

Of course, there's also the need on our part to cater for MANY markets and customers types, so we likely will never be able to simply offer the one-click approaches to the same extent as others with smaller goals to tackle will be able to: latitude and flexibility will always have to be an option, and that doesn't make things simpler.

This said, hearing about how workflows are simpler in corona would be golden, if it was presented properly.

[vlado]

Why it's working selectively?

I wish I could tell you that, but I'm trying to figure out myself But in the meantime, there's obvious stuff that can be improved in terms of ease of use - I still remember that long long thread on setting up matte/shadow objects and I'm the first to agree that it can and should be made a lot simpler. There a couple of similar old and clunky workflows in V-Ray that we have get rid of. However those are separate from the actual rendering technology.

I'd put it this way:
corona is a nice confortable car. A lexus lets say.
vray is a war tank.
People using the tank are just wishing some of the comforts of a regular car to take their kids for a ride without focusing too much in the buttons, and why not, more comfortable seats.
Of couse, when there's war, who cares about comfortable seats? Well...some of us do. But a lexus wouldn't stand a chance.

in December i gave a 3 hours class at a university in the Caribbean on Vray and 3ds max and rendering in general which went very well, at the end there was the Q and A session, another group of guys who run a company and past students now using vray also were there to answer questions, it was to architecture students. Alot of the concerns were about setting up render and time it takes, things they have to learn etc, so many tutorials on vray, why they need to learn about cameras etc when they simply want to present something nice and fast to the client to get the job then someone raised the point about corona and even wanted to give us a demonstration, even the lecturers like the points the students brought up about time and speed and corona this and that. So many people who actually will end up using the software later on don't actually want to know much about sampling, why light cache is there, primary bounces, secondary bounces, adaptivity etc. Alot of people just want to get something nice on the table and they are the ones who are the customers of tomorrow. So why not make it as simple as possible, the bulk of the work is already making and setting up the models, textures and animations etc, rendering should be the fun and fast part. That is how i feel also, fine if you want to argue about dmc sampler all day and why this and why that and look smart to everyone, end of the day most people want to finish the job ASAP, get some money in their pockets and have more freetime. Who loves to be locked up all day tweaking settings? well i guess some do

[super gnu]

i quite like tweaking :P


in any case you literally need to do all of 0 tweaking if you use the vray 3 defaults. set it going.. go and do something else.
