Thea Rendering settings

Postby nicholas3009 » Sun Oct 07, 2018 5:51 pm

Hi, I would like to know from the experienced thea render users for sketchup regarding the render settings as I am new.

What is the recommended engine to use in terms of final renders for architectural spaces and perspectives. I believe IR-Presto is favored towards interactive renders. I was wondering as referred from the Thea manual if the unbiased TR would be the best choice for final renders as its faster and better in quality? (not too sure)

Also, I realised while I was rendering a certain scene while testing out Thea. Is there a progress bar which says how much percentage it has been rendered because I realised the progress bar in between he pause and the stop button refreshes and it seems to go on forever until i hit the stop button.. This is could be a problem if i were to leave my computer to do a batch render and the first renders doesnt complete by itself.. Besides setting the time limit and sampling, is there another way to tell if the render is finished?

next, where are the controls to activate a 'region render' and is it only possible in interactive render mode?

Presto is the fastest. and BSD is the appropriate one for the animation.

I have been using TheaRender (2.1) for Sketchup for some time.

Alas, I have never figured out how to set the render to stop after giving a satisfying results.
It does not function as Vray.

Would you please drop a word on the above, please. I mean, how to set the Presto or ex. TR1 render setting to automatically stop after a minimum time needed to obtain the good results.

Many thanks in advance.

You can do a very small rendering - say 640x... and stop it when the result is ok for you. Thea will give you a number of samples that were taken to render this particular view. You can set samples limit then to this value and render at a final resolution. Once you learn typical values, you will see that usually 512 samples per pixel is enough. For complicated interiors it may be not enough and something like 1024+ may be required. I am writing here about Presto engine. TR1/2 may need smaller values, although they will certainly take longer.

Thea offers also Biased rendering engine, that is not progressive - which means it doesn't ask you to decide when an image is good enough for you, but renders a whole image until it is finished.
