[Max] General Discussion / Re: AMD Ryzen 7 series and Corona?

« on: 2017-04-03, 23:44:14 »

Hello. I do not even know if this is stupid question but I have to know :P

In my country Intel i7 7700K is in the same price as Ryzen 1700. And You propably know what I try to find out ^^

I am working mostly in software like Maya, 3ds Max, UE4, Zbrush, Substanse Painter and of course Corona. I noticed that a lot of software is still running on one core. For example, unwrapping in 3ds max some functions in Maya and Zbrush too.

My whole body is screaming "Go for Intel" because of ~200% stronger one core power but ... I have to check If maybe raw power of Ryzen in application using mutlithreading is worth it ? What do You think ?

Thanks and Cheers !

I Think It's quite safe to say, that you can overclock the ryzen 1700 to 3.8ghz. As far as I know the 7700k can do around 5.0ghz. So the ryzen should be doing about 75% of the single core performance. But I have never tested single core performance in any of the programs.
Regarding multi threaded the overclocked ryzen scores in cinebench around 1600 and the oc'd 7700k score circa 1000. This gives the Intel chip around 62% of the ryzen multi thread performance.

Now you could compare these numbers to the time your cpu is busy doing single vs. Multi threaded work and you should get a rational answer which cpu saves you more time overall.

Personally I'm biased towards the ryzen 1700 since I just got one (upgrading from Xeon e3 1231 v3) and everytime I hit render I can't help but smile :)

General CG Discussion / 3ds Max different uvw maps on one object

« on: 2017-04-02, 15:40:34 »

Hi there,

quite regularly I come across an issue with uvw mapping in 3ds max, for which I can't seem to find the right Google search for to solve it myself.

Let's say you have a couple of instanced chairs that are not properly mapped.
 If I didn't care about the instances, I could just go to the sub object level, select some polygons, apply the desired mapping, collapse everything and repeat that process until the whole object is mapped correctly.

But if I want to keep the instances I can't do that.
I think I could use different map channels, but as far is I understand, this would make it impossible to use a material on two objects with different map channel structures.

In the official interior rendering tutorial on YouTube Ludvík almost would have shown a solution, but luckily for him (and unfortunately for me) his chairs where mapped correctly.

Do you guys have any methods on hand that keep the instances alive, and allow for the applied material to be used on other object?

Any help or suggestion what to search for is highly appreciated!

Hi everyone,

i have had this issue for the second time now, so i thought i might ask if anyone has ever come across this.

As you can see in the attached image the reflections on the black metal beams sort of start over again for each individual piece of geometry. As far as i know reflections don´t work that way on perfectly straight surfaces... :D

The model was created in Revit 16 then linked and imported to 3ds Max 16 as an fbx file.

I would be happy if someone has an idea!
