Simul Support ExchangeCategory: External Plugin IssuesUnity, changing values during runtime.
Marko Barthel asked 1 month ago

I’m having trouble to change trueSKY (version 4.3) values during runtime. The “old” code from version 4.1a does not work anymore. And I tried also the KeyframeTesting.cs script, but it does not find any cloud keyframes in the sequence.This is the old working code from version 4.1a.

if(tS != null) {
    int numj = tS.GetNumCloudKeyframes();
    for(int i = 0; i < numj; i++) {
        uint uid = tS.GetCloudKeyframeByIndex(i);
        tS.SetKeyframeValue(uid, "cloudiness", Cloudiness = Mathf.Lerp(0f, 1f, sliderCloudiness.value));

Hi Marko,

Thank you for your question.
trueSKY has moved away from the use of indices in favour of UIDs.
I have spoken with the team and we need to address the function naming convention in Unity.
Please amend your code as follows:

if (tS != null)
int cl_uid = (int)GetCloudLayerUIDByIndex(0);
int kf_num = tS.GetNumCloudKeyframes(cl_uid);
for (int i = 0; i < kf_num; i++)
uint kf_uid = StaticRenderGetKeyframeByIndex(cl_uid, i);
tS.SetKeyframeValue(kf_uid, "cloudiness", 0.5f);

Please be aware of this new class that interfaces with the DLL: TrueSkyPluginRenderFunctionImporter

Please let me know if you require any further assistance.
Best Wishes,

Thank you for the quick response Andrew. Tomorrow I’m back at work and I can try these changes to the code.
