I take my hat off to your patience and interest. Sorry for the misunderstanding and thanks for sharing your experience. Im not a mean person. I just didn't understand why did you ask all of those questions before. 

I heard that resizing method but i thought it doesn't work well. I only use iray render, i dont know others. But i guess best one is iray at least for daz. 

Yes using many light source make things worse puting them together in another program good idea. 

is it possible to reduce texture resolution on daz?

I am using the latest version. Do you think older versions have better features that last versions don't?

My graphics card memory is 8gb. I know it's not so good and using windows 10.

"""My comment to you that you felt is a threat was to show you how your response on these forums can affect how much people support you. When someone takes the time to contact you about something, be respectful and helpful. That is good customer service.""" I respect you from the beginning. I don't think it's right to judge people this way. I mean they should't judge you by your forum comments. I don't want to be seen as a vendor in forum. That's different thing, of course I am always kinder and helpful to customers. Thanks for telling me this detail though.

I don't know why but picture button just doesn't work. I used before it was working well. But i don't think we need to try to fix this.

Let me explain what does high quality image mean to me. It must be high resolution, at least 2k. Light and shadow and contrast must be perfect. Details must be seen perfecly. So i want to see an image like shot by a photographer. I never able to adjust light and shadow that way. It always look artificial and bad for me in my renders.

""As for the comment about a professional, a professional what"" I was talking about the vendors who do this job for years and make renders like a scene from a movie or photo from a real studio. If i didn't see them, i would think it's not possible with daz.
