Starting new modeling for render(Landscape) , need some help
-
Hello ,
I am an architect . I want to start to make a model of a big residential complex (about 10-20 hectares) contains lots of villas and couple of apartments .
I import apartments models and landscape lines from CAD . I want to render some images by v-ray . I did one of apartments model , and put some sketchup material , and some (I guess) 3d warehouse trees and cars and etc. on it . The model goes extremely heavy and considering a big lag of my v-ray plug-in before starting a render (not responding issue) it takes more than 20 mins to see a preview on 640x480 size . There was no light , or v-ray texture or etc. . There was only skp materials , sun and shadow . But I have to say the file is heavy .
Any way , if this situation remains during modeling the whole site , It will be impossible to finish the job !
Is there any way that I can make a lighter model ? like using other materials or sth like that ? I've heard a lot about not using 3dwarehouse models cause they kill the machine ! but do not know any alternatives.
By the way , I do not want to make a perfect render ,and I do not know how to use v-ray very well (usually just click on render button or change some lights intensity , at best!) , I just want to show some good visions to satisfy the customer , and it has a 10 days deadline , so , not enough time to work on every details .I am just about to start the modeling , so any comment would be so useful , any ideas about how to start the modeling and its process would be extremely valuable to me .
this is a preview of a 3d model which someone made for my costumer and did not satisfied him , so he ordered a new one to me :
So , the model has to be much better than it , (not the buildings details , just the quality of scene and materials would be enough)
And this is the best I could do so far (only a part of site) using sketch-up materials , sun , and shadow , and v-ray render :
Any help ? Any alternatives for materials or 3dwarehouse files ? Any ideas to do it in right or better way ?
I use Intel Core2 Quad CPU 2.83 GHz / 8 GB RAM / Win7 64-bit / Sketch-up 8 / V-ray 1.49.01 / NVIDIA Geforce 210 Graphic card
ps : (to moderator) sorry , I did not know where to post my problem so started a new topic. don't know if it is a v-ray related issue or modeling .

3D trees and plants can be a source for problems. There are some trees in the Sketchucation shop which are optimized for the use within SketchUp (lighter models), maybe you should have a look at them ...

When ever you do decide to use Warehouse models always be sure to clean the model first. Purge it of un necessary layers and dump any useless geometry, like car interiors.
For trees, if you are not seeing them up close, use 2D face me trees, saves a lot of time and keeps the geometry light in the model.
Truthfully, to do a model of this scale you need to be using V-Ray 2.0 rather than 1.49. The new version of V-Ray supports the use of Proxies. This way you can have hundreds of 3D trees with out overloading SketchUp.

Thank you cotty

Thank you TedVitale , using 2D models instead of 3d is really useful , I start to find them online ,this will help a lot for making lighter model .
Unfortunately I have to stick to my vray version 1.49 . So using proxy is not my option
And what about the materials ? I think default materials on Sketch-up are not what I want to use , is there any alternatives I can use instead ?(which is as easy-to-use as sketuchp materials)
And any basic tips that I should consider before starting the project ?

Architecturally speaking, the buildings should be "proxies" too.
What I mean is that the building shouldn't really be there but, instead, just the building shell.
What I do is:
- Create a component with only outside faces of the building, including windows and doors;
- Rightclick on this "building shell component" and "save as" to a folder in your pc;
- This creates a sketchup file from that component in that folder;
- Open the landscape model and go to menu "file > import";
- Import the file you created in step 2/3;
- Insert it on the right place;
- Check if that model is smoother now...

Excellent advice! That will definitely help. As far as materials are concerned, there is a large collection of materials on the Chaos Group website. Log in to download them here: http://www.chaosgroup.com/en/2/downloads.html?s=v-ray-materials
For my personal work when creating custom materials I use http://www.cgtextures.com a lot, as well as http://www.sketchuptexture.com/
Hope that's helpful!

I see that you have only a few days left on this project so this won't help much there. However, before you start a new project I can highly recommend the book "SketchUp 2014 for Architectural Visualization" by Thomas Bleicher and Robin de Jongh.
Even though the book does not cover V-Ray specifically, it has a ton of tips on how to go about creating your models for visualisation that can be applied to any rendering program.
Good luck.

wow ... I think it worked , the model is smoother now . The building was component before and it was a shell also , but what just happened ? I'm curious

Thank you again TedVitale_CG
I tried using kerkythea for render and it was good , I mean it was very easy to use , can I use it instead of v-ray ? What do you think about this software ?
-
I deleted all trees in my model and it is totally smooth now ! I think as Cotty mentioned it is the main problem , using 2d trees should solve it

Plain and simple - Warehouse is full of crap. I would open each Warehouse file independently, clean as suggested above, try to render it VR by itself and ensure there are no errors. Also make sure you are the latest 2.0 release as there have been issues in the past with materials missing and then renders go blank.

Well for your level Kerkythea is definetely worth the try! You'll improve the level of your rendering and won't notice a difference as Kerkythea has everything you'll need in a medium term. Other software packages, however have so many more features that they can't compare.
Most of them like Vray, are competing at another level. I use Thea myself and it's great! But there are so many excellent choices...
Explore Kerkythea, and when you feel the need for more explore every option available...

yeah , that's what I need , thank you for your help . I started the project , maybe make some test render in couple of days
