what is the size of your lights??
20000 subdivisions is a large number!

what are you qmc settings?

**RErender** · 01-06-2005, 02:35 PM

20,000 is not that much for PPT

I don't think there is any of what you are asking for, Priad. PPT is pretty much just set it high and forget it. It is more of a toy than a reliable method. I think you'd be better off just using high GI settings with the conventional methods.

**jacksc02** · 01-06-2005, 02:40 PM

Ooops it was my mistake, i misread his post, i thought priad had said that he had 20000 subs on his vray light!

time for a coffee i think

**priad** · 01-06-2005, 03:16 PM

Thanks.
Finaly I just would like to know if PPT is interesting?
Eric, you don't think?
lightcache is the smooth GI thing, I like it but...

**priad** · 03-06-2005, 03:27 AM

with many night of PPT I don't have success with it in 16h and more...
Here the render do in 3h with traditional method and normal setting (lightcache subdiv 4000 with use it for glossy), irmap high setting but -3/-2, without too noise on the ground and a good displace.
Lighting is with one IES sun.
This is an empty test scene don't care about the bed and model.
How does we need to use PPT, why?

**DaForce** · 03-06-2005, 04:13 PM

PPT calculates an infinite amount of light bounces and offers the most accurace/realistic lighting. But it also takes alot longer.
You can come very close using other methods, and as RErender said its more of a toy.

Its kind of funny how many people have gone crazy and are in love with PPT when its not really any good for production (Im guessing this is what you mean when you say its a toy).

Everyone loves new toys but i'm guessing there must be a lot of people out there who give the impression they are an elite 3D artist who swear by PPT but actually dont use it for anything other than a personal hobby. Hard to know when to trust peoples opinions with this kind of thing online when everyone uses it for different purposes.

So for Architectural visualisation, do you guys reccomend staying away from PPT for a while? I trust the opinions given in here much more than any other forum because most of you actually work in the industry (as opposed to other places full of backyard 3D elitists who constantly say their way is better regardless of the facts)

Why even ask the question? You are the one who has to determine whether a particular type of rendering or program fits into your pipeline or not.

To me it sounds like you have a sort of contempt for people who experiment with other methods or renderers. I have had people ask me why I went from using this or that renderer to this other one. You know what? It's none of their damn business. In the last 2 weeks, I've used VRay, mental ray, Maxwell and VIZ 2006 radiosity for production work and they served their purpose. That's all I want.

**paulison** · 03-06-2005, 11:12 PM

Sorry Frances, I've just been given a lot of bad advice and I agree what you say is correct....trust your own judgement. So many not beleiving everything you are told is the best approach

The contempt comes from constantly being told by people that my work is crap and inferior to their work and that the way im doing things is wrong. This is due to the fact that i still model in ArchiCAD and export to viz which is apparently the most offensive way of modelling possible to anyone modelling in more advanced software. It just seems that with PPT there has been a similar attitude about it being the ONLY way to go by people who dont actually use it for production work. It is good to have an honest response finally about PPT that it is more of a toy than anything at the moment. Just had to say something and say thanks to those guys who gave that good advice

I apologise though, certainly didnt mean to offend. I think its great if you are in a position to adapt the software and approach you use depending on the type of project. Im still new at this so dont have those options.

Forum is here to share all our own opinion, follow its own jugement is better but sometime it's important to clarify some thing.
Everyboby can put this finger on everything but sometimes we miss reality.
If the conclusion is :"you can let the PPT only for your hobby, it's accurate but workflow is to long" ok, I have make some test in my loose time and I don't think that I have really loose time

some people have big influence in this forum and we must know all the issue. I love this forum because there are some judgement and experiments.
When Vlado had add PPT to Vray some people says: wow thanks etc... ok all new feature must to be test, they aren't here just to play (I think) If it's just a answer to Maxwell addict, sorry I haven't understood.
And it's important to clarify.

**priad** · 04-06-2005, 01:00 AM

just an other thing, I think that all new feature are here to be improve so to play with to have an opinion

I agree completely.

New features - whether or not 'toys' are fantastic assuming that it will hopefully add to a program's development/productivity over time. That said, Vlado and the team have done an outstanding job addressing concerns and needs within the Vray community. I think that PPT is a side-project attempt answer Maxwell's method of simplicity one-touch rendering. Maxwell in the meanwhile will continue to increase speedwise (as this is a full-time method for them.) I hope PPT can achieve the same or better. I'd hope that Vray can eventually reach a point of:

1) increasing image quality
2) increasing the already fast rendering times
3) making the dialogs simpler/more streamlined while performing the above.

Are they criticizing or asking because they respect your work? If it's the first then I agree as well. I let the opinion of some software 'elitists' roll off my shoulders. I've been getting alot of that from various fanboy members of the Maxwell community recently. Personally, I take the 'whatever works' best approach.

**paulison** · 05-06-2005, 01:39 PM

Hi jujubee, I also agree that new features are fantastic (and essential to keep progressing)

My only issue was with people being so defensive about their method that they feel the need to force it onto others, even if it isnt the ONLY way. The maxell fanboys was a good example but im also talking about MAYA people who say max is crap for modelling (as another example) etc etc. Its not good when these people lead to you second guess your own methods which starts to negatively effect your work. Theres a lot of examples but in relation to PPT I think it was good to hear an honest and unbiased opinion about it (which is the only reason I posted) which is one thing this forum is really excellent for compared to some others.

maybee when the whole multi-core processor thing takes off we will be using PPT and producing even better work in resonable timeframes

**Metin_7** · 10-06-2005, 03:16 AM

Hi to y'all,

In the scope of this discussion I invite you to have a look at this thread, especially Vlado's comment regarding PPT ...
