Hi,
I would appreciate suggestions for improving this render.
There are some obvious things to fix, like the tree branch upper right.

My client already has this and is satisfied, but I think it will be a good learning tool for me.

I think I would like to photoshop in the grass, but have not found a good images to use for that..any direction for a good source for grass images would be appreciated.

One of the problems with this particular render is that it is taking 22 hours to cook.
I am thinking it is those big 3d trees in the background.
8 core, 64gb ram, solid state, etc.,
I seem to remember seeing a plug in that looked at the size of materials & stuff in the model so one could evaluate where fat could be cut. Anyone know the name of that plug in?

Thanks your help.

I don't have much experience when it comes to exterior rendering.

But if you replace the trees in the back with 2D trees or just a nice backdrop, and remove the planting in the front. Render time wil decrease a lot! 

You also want to kill the lights.

Hi Paul, yeah, this render should take 5 min to render.

A few tip to make it quicker and better;
Like Gijs said, loose the 3D trees and vegetation on the background and foreground, kill the light (almost got used to interior light during day, but now in an exterior render! [smile]. Make sure you use the physical sky 2, and boost intensity/exposure to around 75-90%. Use a more realistic glass setting for windows and model quick wall inside so we don't see through the building. You also need better modeling/materials for the wood elements. Not sure if it would be real wood, it would not be exposed like that. Plus some reflection would go a long way.

Hi Paul, you did a fabulous job, great modeling!
Gijs and Nick gave you some good advices for improving the model.
I Will talk a bit about PP. When I look to your picture our eyes are guiding first to the center, then on the left and bottom where the vegetations are.  
This is because of the lighting. With PP, you can easily fix that and probably flatter a bit more this beautiful house wich should be the only star.
You should experiment with a darker vignette, on colors with an overlay brush, saturation and highlithing. Those small adjusments won't make the render more realistic but they give more common sense and improve the feelings.  
I couldn't resist and quickly did this. Hope it could help.

I am re posting this reply, because the previous did not seem to display correctly. 

GijsParadijs,

I think you are correct, replacing the background trees with an image will help render time. I have had a hard time in the past finding backdrop images that match the atmospheric lighting on the model or vise versa. I have just avoided it rather than mastering it. I guess it may be time to stop avoiding it.

As for the lights. I like them. I really do believe that turning some lights on even when I would not do so in the real world is ok. It adds a life and sparkle to the scene and clients think it is magic, and in a way, it is.

Nick,
Thanks for the tips. It will actually be exposed wood that is stained, but I am not representing it very well. 

Archi_3d,

I love what you have done! I will learn this presentation technique. It is exactly what I would like to present in most instances. 
 I tend to shoot for photo semi realistic vs photo real. I understand the desire to produce a true photo real image and the challenge that it presents are a noble and fulfilling exercise, but I generally stop at the happy client stage because that is when money usually stops changing hands.
 
Having said that, I must continue to incorporate techniques that will better my renders without adding significant time to the project. 

Thank you all three of you for your help.

paul

Thank you Paul [smile] I'm glad you like it.
Exploring different techniques, always looking or asking for new stuffs are the keys... I like your style, keep up the good work!

I would suggest rendering one image with lights off and another one with vegetation layer off. Then compare. I am almost certain that the lights are the problem. There are 14 light sources that I can count with potentially more out of the view. Vegetation only renders relatively fast. I was able to render 10 milion faces of vegetation on 1920x1080 in about half an hour on my laptop.

Pmolson, you put a lot of work into your modelling, for me that's where you start to see the difference from a good to a great image, keep going with it!

I agree with DavorP, the lighting is most likely your problem with render times. Nearly all of my renders are external and my max time is around 3 hours rendering at 4K resolution on a laptop. Turn off the lights and try a test to see?

And as I write this, I have just noticed when you originally posted this... Maybe you have already fixed the issue!

Davor and Ennvee,

Thanks for your suggestions.

I think there is some truth to what you say. I ran a quick analyse on the model and it appears I have some lem materials in the model which should not be there.

There are interior items in this model that one does not see from the exterior render and I have those layers turned off for the render, but I must have inadvertently imported some large lem surfaces from the interior renders that I borrowed furniture and such from.

I have not had time to investigate, but I bet those, coupled with the large 3d trees, (I have rendered these before and I know they exponentially slow down the render) are the culprit.

I will clean things up and run it again as soon as I can remove my nose from the grindstone.

Thanks!

Ok, I did some experimenting.

original render = aprx. 20 hours.

1. Replaced a lem material that was applied to 1440 faces (I honestly do not know how or why that happened. I started another thread about that.)  render time dropped to 5 hours. 


2. removed big 3d back drop trees.  = render time dropped to 2.5 hours


3. removed all lighting  =  render time dropped tp 45 minutes.

Thanks for your help youall!

Wow the 3D design of the house looks great, the modern carpet manufacturer also use such 3D designs and techniques for designing their carpets and rugs to match the required theme.

@lorendyer How is this carpet manufacturer relevant to this topic?

It's not - it's an attempt to be subtle while spamming.

It failed [smile]
