Rendering issue

Gathar

Hello,

I'm trying to render my map for Shessar contest, and I have a strange artefact happening right in the middle of the map. I attach to this thread a very small sample of this issue.

If I have to describe it by words, it looks like the map is rendered in several parts, and the parts don't match correctly:
- The grid appears doubled at this place
- The lighting in the upper part of the map stops brutally and is not propagated to the lower part

Am I right in my assumptions?
If so, what can I do to prevent this? Is rendering to a lower resolution going to help? When should I stop? Or maybe a higher one?

You are correct that the map is rendered in multiple parts. Unfortunately, effects where the source is in a different part from the piece currently being rendered doesn't carry over, which is especially troublesome with lights.
Rendering it in a lower resolution will help, but might not completely fix the problem.

What I did for my own map was that I maximized it on a 4K display and took a screenshot instead, cropping it in an image editor before posting (for an appropriate image size to embed in a post, even a full HD screen will suffice).

I've noticed how lighting doesn't seem to get remembered between separate passes.

How many passes does it do when you render it?

Oops - took too long thinking... sorry Remy!

Would it help to increase the maximum Pixels Per Pass in the file CC3PlusCfg.xml?

That's what Ralf showed me how to do when I was getting artefacts in the MC map.

How about printing to PDF using a PDF printer like PDFCreator then using GIMP to convert from PDF to JPG or PNG? I have not tried GIMP to do this but apparently it is possible according to this link (method 2):

Printing to PDF is my preferred method when it comes to saving maps and I don't think I have noticed any weird rendering issues.

Ralf has just confirmed the following to be a good general solution to eradicating artefacts caused by multiple pass rendering, as seen in Gathar's picture at the top of this thread.

1. Close CC3

2. Go to your Program Data file. For most people this will be C:\ProgramData\Profantasy\CC3Plus

3. Locate the file called CC3PlusCfg.xml NB. Take a copy of this file and keep it somewhere safe in case this doesn't work for you on your machine or with your setup

4. Right click the file in the CC3Plus folder, and go for 'Edit', which will open the file as a text file.

5. Providing you have already rendered at least one map with your software you should have a block of HTML code right at the end of this file that looks a lot like the attached image.

6. Add the extra zero (highlighted yellow on the attached image) to the end of the number (you will have only 6 zeros, not 7), then save and close the file.

7. Reopen CC3 and try your render again.

Thank you again Sue, I multiplied it by 10, as suggested, and it solved the issue
Thank you also Monsen & Mappy for your suggestions. I haven't tried them, but I'll remember them if this issue arise in another context.

Oops - I made it look like it was my idea!

Ralf provided the solution to me a few weeks back when I was having difficulties rendering Merelan City. So really the thanks should go to Ralf
