[Max] I need help! / Corona Crash

« on: 2014-12-10, 19:01:02 »

When I render individual items in "isolation mode" Corona renders fine.
But, when I render the whole model Corona parses to 1:38 and stops, the computer lags terribly and I have to cold start the computer.

My Max file size is: 574Mb
I have an (.7) chip and 12 GB of ram.
I have Corona 7.2

Is my model too big?

When I select an object to be converted from Vray.... and press the Corona Material Converter... everything in the model turns white.
I just want to convert one item... not the whole model.

Is this possible?

[Max] General Discussion / Corona Pricing

« on: 2014-12-05, 09:30:00 »

I thought I would write this down and get it off my mind.
I really want Corona to succeed cos it is a great product...and makes (me) look good to my clients. But, for someone like myself
who lives in a third world country it is too expensive. I am hoping you bring out a condensed version of Corona that has less features
but still does the job at full resolution so it's more attractive as a purchase.

I feel Corona (potential price) is aimed at the European market.
Judging from the forum, people from all over the world use Corona... so it's in your best interests to keep the price affordable for those that do not command Euro earnings. Some things to consider...

1.  A stable Corona crack will be available within 24 hours of beta release. Though cracks are frowned upon in Euro-land
they are actively encouraged in third world countries. Only one shop (Virgin) sells DVD's and games that are not pirated in Egypt.
It's just the way things are here.

2.  Most people in the 3rd world earn 50 Euros a month. I live in Egypt and a good wage is 100 Euros a month.
As a full time art teacher (my first year here) in a good school I earned 500 Euros a month. This is good. Mostly all software in Egypt is cracked.
So, when you think of the whole Middle East, South America, Africa, Russia, India etc.... a massive market. Piracy is riff in these countries cos software prices are out of the reach of most folk.

3.  CG is not cheap. You have to buy a good computer, big screen and laptop as well as the software....
3Ds Max, Adobe Suite, AutoCad as well as a render engine.

4.  At first most of your core users will be freelancers. Who barely get by. If Corona is to flourish it needs to be a render engine made by the people, for the people. This is what attracted me to Corona... it seemed revolutionary not just in colour mapping but in having it's feet firmly on the ground and being close to the troops.

I was referred to Corona by another CG designer. I read up on Corona and read that it is free for now but when it becomes beta it will be
at an affordable price or some form of free version. I weighed up the pros and cons and decided to invest in Corona and leave Vray behind. I was abit shocked when I read your news on pricing structure for the beta release. If I was living back in the UK it would not be a problem, but here in Egypt, it's a spanner in the works.

I don't mean to ruffle feathers.... and like I said.... I love the Corona simplicity and colour mapping system. I live in a culture that is cash orientated. People pay with cash only and don't trust banks or have credit/debit cards. So the Corona subscription route is impossible.
The only way forward for me is a one off license.

[Max] General Discussion / Material Converter Wishlist

« on: 2014-12-03, 12:37:32 »

DeathClown has made a great script with the Mat Converter.

But... all models I download have Vray textures. Which means I have to strip them down and apply Corona Mats.
Is it possible one day the coverter can auto convert model textures in the future? Or is this impossible?

I say this cos people are starting to create scripts for Corona, like the wonderful new script: Region Render: http://www.scriptspot.com/3ds-max/scripts/regionrender

Off-Topic / Invert a map

« on: 2014-11-27, 08:25:28 »

Does anyone know how to "invert" a specular map in Max.

When using Arroway textures they tell you to invert certain maps like Specular for better results.
I know how to do it is Sketchup, but not Max.

Thanks.

[Max] I need help! / Composite Maps

« on: 2014-11-24, 09:39:11 »

I read Edvards post on how to use Composite Maps with great interest:
https://forum.corona-renderer.com/index.php/topic,4031.15.html

But, I still feel I am flying blind and don't know what I am doing.

Do I use the Comp-Map to blend one layer into another layer using the opacity dial to bleed one into another? (See screenshot1). Is layer 1 ontop and layer 2 below?

And why do it this way when you can do it like this (See sceenshot2). What is the best way to blend bitmaps togther to create a distressed look using this technique?

Hopefully, someone can inform me on this :)

Work in Progress/Tests / How to use backplates?

« on: 2014-11-22, 15:57:08 »

How do I use Corona Sun and put a cityscape backplate behind the glass?

I want to combine the internal reflections of the glass combined with a backplate if possible in Corona and not have to do it in Photoshop. I have looked at the Vids about this but it talks about using HDRi not backplates.

Do people on this forum use Corona Sun or prefer using HDRi images? Or combine?
Is it possible to render an image with the glass windows blocked out incase I do want to put it into Photoshop later and put an image behind?

Also, how do I get rid of the info on the bottom right of the render?

Thanks

PS - The materials are not finsihed... this is just a test image.

[Max] I need help! / How long to render

« on: 2014-11-21, 18:34:13 »

I know it's an open ended question.... but how long should I render an image.
What I am asking is how long do you guys leave a render on... a few hours or all night?

I am asking cos I have an iMac and it gets red hot when I render so I want to keep render times to minimun.

Thanks.

[Max] I need help! / Dirt and scratches

« on: 2014-11-21, 18:28:15 »

What is the correct way to add dirt and scratches to materials?
Do I put them in a specific slot. If not, what Corona Map do I use to create dirt effects?

Thanks.
