Please see the System Requirements page for more information on the minimum and recommended system requirements for Knald.
Knald periodically requires an active internet connection in order to contact our license authorization servers. This check is preformed to ensure that your machine is authorised to run Knald and once license authorization has been confirmed you can continue to run Knald off-line until you wish to update the software (when an update is released)
To ensure that the servers can be contacted please ensure that the following addresses and ports are assessable from the machine Knald is installed upon.
Many studios and university networks sometimes block the ports required for Knald's license/authorization process - please contact your network administrator to ensure the required ports are open and any proxy servers are not blocking HTTPS traffic for the above addresses.
If Knald fails to contact the servers you will get a grace period of 5 days before Knald fails to start. Upon contacting the license/authorization servers Knald will once again work correctly. You only need access to our servers for initial activation and not to run Knald on a day to day basis.
Here are some things you can try that might help you out:
Some NVIDIA drivers have been reported to cause problems with OpenCL. Please do not use the following drivers with Knald as they are unsupported by us.
On some occasions errors within Knald are due to cached shaders that the driver hasn't compiled correctly or are corrupted in some way. Whenever you install a new driver we always recommend that you perform a clean installation and delete any cached shaders if they are present on your system.
Performing a clean installation of your drivers and deleting shader cache is simple and you can learn how to do it on the Clean Driver Installation page
If you are still having issues, please contact us! You can reach us via e-mail at: support@knaldtech.com
In the case of any of these issues, please check the following:
Below you will find a rough guide of how much contiguous VRAM is required on a single GPU in order to process the various texture sizes listed1)
Striations such as these are often due to the bit depth of your source images being too low. As a result of this limited precision, it can be difficult to reproduce variations of angle and slope with acceptable accuracy.
We suggest the following solutions to fix these issues:
This is a side-effect of Knald applying the integrated height map to your mesh. Sadly, it is not currently possible for Knald to generate perfectly correct values around the UV islands (which are typical if the normal map was baked) resulting in the possibility of minor visual aberrations when applying the exported height maps to UV containing meshes.
