I want to turn off rendering while I adjust the scene.

badoidge

Apologies in advance for not speaking your language as far as this stuff is concerned.  I'm totally new to anything like this.  (I'm not going to sound smart in this post.)

Anyway, I created a character, put some clothes and hair on her, shaped, etc.  Now my objective is to put her on the bed and have her looking out the window in an environment, figure out lighting eventually, and make a photo.  Starting out.  The problem I'm facing is that I must have turned on some setting, Iray or whatever, that makes my character look like it does when I do an image.  Everything is running excruciatingly slow now, and my machine is no slouch (5900x, RTX 3080, 32gb RAM).  With every rotation, change of perspective, learning to change the location of my character, I have to wait forever while I'm watching big fat pixels turn into the way my character will look like in a render.    How can I get back to crap mode, low resolution, bad lighting, so I'm not waiting all day while I put things in their proper place, get the pose right, and get the character in the right location in the environment?  How do I toggle 'looks good' on and off?   Does that make sense?  I want to put things in order before I preview the finished product, and I don't want to sit here and wait while things are pixelated af because I've rotated the view 5 degrees or moved the character three feet to the left. I'm looking at these tutorials and trying to put in the right search terms and looking up glossaries, but I can't find or understand any answers.  Yes, I understand that Youtube is a great resource and I wouldn't be on here if I found the answer.  So...crap mode:  Is there a way to get back there?

At top-right of the Viewport, just to the left of the button that lets you pick the view to use (Perspective View or Default Camera usually) theer should be an Iray or Filament logo - click that and pick a different Drawstyle, or hit ctrl 9 (cmd 9 for Mac) to switch to Texture Shaded Drawstyle.

In addition to what Richard said...  Filament can be an extremely useful engine because it's extremely quick and it gives you a pretty good impression as to what your render is going to look like (even Iray renders; though some details may differ). The only issue with Filament: default lighting, things can easily look seriously overexposed.

If that also applies to you: open the 'Create' menu and add a "Filament Draw Options Node". While having this node selected in your scene go check out your Parameters tab and bring down both "environment intensity" (default 1500) as well as the "Distance scene light scale".

It's not directly related to your question I suppose, but figured I'd mention it anyway because... Filament can honestly be quite useful, especially because it's a heck of a lot faster than Iray.

This will be a catch-22 thing...

You only adjusted it 2 to 3 degrees, "because" you saw what it looked like rendered, and it only needed a tiny adjustment.

You can hide individual items so the preview renders faster too... While "modeling". If the items in question are just a chair an a person in a full house composition... Hide everything other than the person and the chair. :)

Your biggest issue will be using openGL mode, vs IRAY, where that lighting from IRAY just isn't "tuned" to match GL lighting, and many light sources just don't have a GL counterpart. You'll be stuck using the camera-light to set things up and fighting anything that should be "transparent", which just isn't showing as transparent, or it's just totally invisible in GL, due to flipped-normals and GL's inability to render one transparency item through another in "fast mode".

Another tip is that you can setup "multiple viewports", which is common in most 3D programs. One is usually "camera", and three others are usually TOP, SIDE, FRONT, or just other cameras with "wire-frame" or "shaded" etc... You can setup different "views". One for "scene setup" and another for "test rendering". The prior having NO rendered output, the other ONLY being a rendered output view.

It could help your workflow too.

Unfortunately, Daz has not given us a seperate panel for controlling IRAY-PREVIEW settings. So any setting you have for "final renders" are being used for the PREVIEW also.
